NAME
Acme::What - the f**k?
SYNOPSIS
use Acme::What;
sub WHAT { warn @_ }
what is happening?
what is the problem?
WHAT?
Acme::What installs a new `what` keyword for you.
The `what` keyword takes the rest of the line of source code on which it
occurs (up to but excluding any semicolon), treats it as a single string
scalar and passes it through to a function called `WHAT` in the caller
package.
So the example in the SYNOPSIS will warn twice, with the following
strings:
"is happening?"
"is the problem?"
If you'd rather use a function other than `WHAT`, then that is OK. Simply
provide the name of an alternative function:
use Acme::What '_what';
sub _what { warn @_ }
what is happening?
what is the problem?
Acme::What is lexically scoped, so you can define different handling for
it in different parts of your code. You can even use:
no Acme::What;
to disable Acme::What for a scope. (The `what` keyword is still parsed
within the scope, but when the line is executed, it throws a catchable
error.)
WHY?
It's in the Acme namespace. There is no why.
HOW?
Acme::What uses Devel::Declare to work its magic.
WHITHER?
Devel::Declare, Acme::UseStrict.
