Perl6, modifying @*INC

[molecules]

I was going to try to help flamey with his LWP::Simple problem. However, I had a different problem. I need to modify my @*INC, but have not been successful with it. Here are a couple of my attempts:

use v6;
BEGIN{ push @*INC, 'C:\Rakudo\lib';}

use LWP::Simple;

This gives the following error:

===SORRY!===
Confused at line 2, near "BEGIN{ pus"

shell returned 1

I also tried:

use v6;
push @*INC, 'C:\Rakudo\lib';

use LWP::Simple;

Which gives the following error:

===SORRY!===
Unable to find module 'LWP::Simple' in the @*INC directories.
(@*INC contains:
  C:\Documents and Settings\HP_Administrator/.perl6/lib
  /Parrot-2.5.0/lib/parrot/languages/perl6/lib
  .)s ENTER or type command to continue

shell returned 1

I am using Rakudo Star, installed on Windows using the MSI installer.

UPDATE:
On my Linux installation trying to use the BEGIN block also gives an error. However, LWP::Simple is already in one of the @*INC paths.

UPDATE 2:
Just a note that it is actually more intuitive to use unshift instead of push when modifying @*INC. This puts your added path at the beginning of @*INC, where it will be given precedence over "default" paths.

BEGIN{ push @*INC, 'C:\Rakudo\lib';}

Add a space before the opening curly: BEGIN { @*INC.push( 'C:\Rakudo\lib' );}

The reason is that {...} directly after a statement is parsed as a postcircumfix, which is very handy if you want to access hash elements like %hash{$key} (but which is intentionally not special-cased to hashes).

The error message could be improved, though.

Thanks!

I also noticed that the indirect method syntax for push doesn't work inside the BEGIN block. I wasn't sure if that was a feature or something still to be done.

[moritz]

It's a well-known bug. Unfortunately we have some roadmap items to complete before we can fix that - we need to have static lexical pads at compile time to make built-in functions available in BEGIN blocks.

That (the indirect object syntax, not the missing space) looks like a parsing bug. I managed to get things to work with:

BEGIN { @*INC.push( 'C:\Rakudo\lib' ) };

You might want to ask on #perl6 if this is a known bug.

Update: parenthetical note added.

Thanks!

UPDATE: Also, thanks for all of your work on Perl6.
