Yes, Smalltalk is just like Lua here.

Richard,
Question from someone still fairly new to Smalltalk:
To implement the example you gave regarding mutually recursive functions in
Lua, one must write something like this:
local f, g
function g ()
f()
end
function f ()
g()
end
where the
Suppose you want a pair of mutually recursive functions.
They have to be able to name each other.
In languages like Python and Ruby, you can have
methods AND you can have named functions. In fact
Python had named functions before it had objects.
But in Smalltalk, you have methods, which cannot be
Hi,
Blocks are very useful when you need to evaluate code from an outside
source.
For example a BPM Process that have gateways with different conditions.
To the Smalltalk system conditions come as Strings and convert them to
Smalltalk objects is very easy:
self evaluate: '[:process | process amou

On a similar line - I’ve often noticed that an interesting block pattern in
Smalltalk which is overlooked in other languages is how we handle errors
through them.
We often don’t throw exceptions but instead pass a useful block (and often 2)
for what to do instead.

Hello,
I tried to upload a stack trace with playground with upload to cloud
but I see then a 400 bad request error message.
I was a file of 3Kb.
Is there a alternative so I can upload a stack trace.

Hi,
It is an important restriction on Python. So Javasctip has several way
of doing lambda, correct?
Thanks

Hi,
Thanks to all for information, this is finally fixed.
On Centos 7.6 the fix is:
sudo ln -s /usr/lib64/libcurl.so.4 /usr/lib64/libcurl-gnutls.so.4
In process i also executed (not sure if it had a direct impact on the fix):
sudo yum install libgit2

Thanks for the links, i will research further on this.

One point worth making is that Python lambdas are artificially restricted:
the body of a Python lambda may only be a single expression, not a sequence
of statements. This restriction is for ideological reasons (the BDFL does
not *want* you to do that) not for technical reasons. Lisp and Algol 68
In javascript I believe is
var f = function(x) { return Math.cos(x) + x; }
var df = function(x) { return f(x + 1e-8) - f(x) * 1e8; }
Best wishes,
Tomaz

Hi,
We, Smalltalkers, use bloc of code as easily as we breathe air.
I am writing an article on Smalltalk programming for a French
mathematics teachers magazine.
To illustrate the simplicity of Smalltalk, I would like to compare how
the bloc of code 'f' and 'df' below will be implemented in Javas

Hi Alistair
I will look when have a time.
But you can try to write a test for bitmap serialization/materialization in
TostSerializationTests (if I remember correctly the name).
It will show if bitmap transport requires extra logic.

Hi Denis,
If I print:

which is obviously correct, but:
remotePharo evaluate: [ Bitmap withAll: #(42 42 42) ]
gives me a bitmap with all zeroes (running it locally does the expected thing).
I can see that the bitmap is bein
