mauke gave a bunch of nice reviews, and while working on input validation, I wrote this down:

defined($_[0]) && (reftype($_[0]) // '') eq 'CODE'

... the the fact undef might be returned from reftype() makes me want to use Paul's string equ operator[1] instead:

defined($_[0]) && reftype($_[0]) equ 'CODE'
