NAME

Slang::Otherwise - Slang to add 'otherwise' block to 'for' loops

SYNOPSIS

This slang adds syntax for an otherwise block that will run if the for loop is not entered.

use Slang::Otherwise;

for dir.grep(*.basename.contains: 'xyx') -> $f {
    say "Found $f"
}
otherwise {
    say 'Got nothing'
}

CREDITS & NOTES

This code is shamelessly taken from a blog post by Damian Conway.

Damian's slang called the block else, but the post spawned some discussion about whether that is a good name, also taking into consideration that Python's for/else does something entirely different. In commenting on the article, several people suggested otherwise, which is a good a name as any.
