I know very little about subroutine attributes, so you're going to have
to investigate that one.
Keep in mind, though, that we want the *whole call t

My point is that the CPAN Testers reports for fails have the output of
make test, eg:

Its not specified yet, how eval fits into the picture.

Q1: Suppose I have the following call into a sub named "foo":
foo($var1, $var2, $var3);
What should I set in I1? Is it 3?
And here:
foo($var1, @arr2, %hash3);
Is it still 3, since these aren't gonna be flattened?
Q2: I'm calling without prototyping
foo($var1, $var2, $var3, ... , $var23);

Considering that parrot is now emitting an executable (on some
platforms)... and IIRC, C will be one of the languages we plan to have
parrot support for... will parrot be able to compile itself? :)

It's missing some things. One of which is the (currently used?) way of
preventing infant mortality: anchor right away, or else turn off DoD

Hey all,
Python objects can have things "in" them:
foo["x"] = "in"
... and it can also have things "on" them:
foo.x = "on"
I noticed lua treats these as the same thing
and got curious about the distinction in IMCC.
Coding it this way seems to work, but I'm
not sure I really understood t
