Re: callbacks with placeholder vars

There's this much: https://docs.raku.org/language/variables#index-entry-$$CIRCUMFLEX_ACCENT > If you have self-declared a parameter using $^a once, you may refer to it > using only $a thereafter. But it doesn't go anywhere near far enough. You *had better* to refer to it as $a or you'll get

Re: callbacks with placeholder vars

Okay, so my central confusion here has to do with not understanding that the caret gets used *only once* in a construct like this: my $cb = { do if ($^a eq $^b) { "$a"; } else { "$a & $b"; } }; say $cb( 'a', 'b' ); After $^a is

callbacks with placeholder vars

Here's a simple use of a callback that just works: my $cb = { "$^a & $^b"; }; say $cb('a', 'b'); # a & b Just as an aside, it's interesting that this would be an error: say $cb('a', 'b', 'c'); # Too many positionals passed; expected 2 arguments but got 3 The

use lib and locations in a variable

I want my test files to be able to find the modules they're testing just using their relative locations, given the usual layout of "lib" and "t" locations in parallel inside the project directory. I find that while this works: use lib $*PROGRAM.parent.add('../lib'); This doesn't work:
