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.
