Re^5: "warn" is your best friend

Aahh, I see now - at the time the leading '::' wasn't abundantly clear (as if anything ever is? :-) How on earth did you find out about that - there's nothing in the perldoc for it ?

Awesome, ground-breaking (for me) discovery.

Many thanx again ... tobyink++++

A user level that continues to overstate my experience :-))

When you do `use Test::More` in a test script, what you're doing is importing all Test::More's functions (including `diag`) into the `main` package, so it can be accessed as `main::diag` instead of `Test::More::diag`. The first paragraph of perlmod tells us that `::foo` is a shorthand for `main::foo`. Thus `::diag` works everywhere in your modules, provided something has happened to import Test::More into main (most likely: you are running your module through its test suite). `use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name`	[reply] [d/l] [select]
