Hi All,
Math problem:
x = 60÷5(7−5)
raku -e 'say 60÷5(7−5)'
No such method 'CALL-ME' for invocant of type 'Int'
in block at -e line 1
Seems raku does not like the (). How do I fix this
and maintain the flow and look of the equation?
-T
The correct answer is 24
Just because mathematics allows an implied multiplication doesn't mean Raku
does -- in fact I can't think of any programming language which does. You
need to stick an explicit multiplication operator ('*' or '×') between the
5 and the left parenthesis.
The reason for the error message is that addi
Good morning/afternoon/evening Rakoons!
Sadly, there was no Rakudo/MoarVM/NQP release in January, so Rakudo Star is
going to use the next best thing, the release from February. This change was
just pushed, and is ready to use.
This is the first release that appears on GitHub as an actual release[

Hi, I want to create a system that will show documentation about Raku
Modules that I have installed.
There does not seem to be a Documentation standard, or best practice,
for Raku modules.
Hence the following post.
In the Modules documentation in the Language section of the Raku
documentati

As a (potentially) interesting side note, while Raku doesn't provide implied
multiplication, it _is_

Something of an understatement, I think. :-)*
Seriously, this made me wonder if inscrutable error messages might be
clarifed by a (reverse) trace of the last few steps in parsing. That
would show you what the compiler thoug

But why do that when you can add a CALL-ME to the number classes that does
multiplication? 😇
Int.^add_fallback(
{$^i.defined && $^m eq 'CALL-ME'},
-> $, $ { * * * }
);
say 5(4); # 20

Not in this case. The error happens at run-time. Syntactically the expression
is a valid one because `5(...)` is interpreted as an invocation. Raku
implements invocation protocol a part of which is method 'CALL-ME' defined on a
class:
class Foo {
method CALL-ME(|c) { say "Foo invoked with

This is some very nice work, of course. I was wondering how difficult
it would be to support other output formats (texinfo, nroff...).

I've got some problems with the existing search, myself,
If you go to docs.raku.org and type "^methods" into the search
window, you get a drop down looking something like this:
