in thread It's so easy to become complacent.

bah, variables are just one of so many things!!!

$ perl -E 'use strict; sub foo { say "hello" }; say "runtime!"; f00()'
runtime!
Undefined subroutine &main::f00 called at -e line 1.

Though I have to admit that not being able to declare variables explicitly (and as result, their scope) is for me one of the mayor Python issues.

That's why I like to omit the parentheses whenever possible: `$ perl -E 'use strict; sub foo { say "hello" }; say "runtime!"; foo' runtime! hello $ perl -E 'use strict; sub foo { say "hello" }; say "runtime!"; f00' Bareword "f00" not allowed while "strict subs" in use at -e line 1. Execution of -e aborted due to compilation errors.` [download]	[reply] [d/l]
