Which of those modules listed export SIG ?

Or are you asking how to implement SIG ?

edit

after looking into the source of Logic::Easy (which has no POD) it seems that SIG is implemented by source filter.

I can't see any mention of multi-methods there ¹ but since Perl doesn't do any static parameter checks when calling a sub², you'll have to construct one single sub frobnicate() which checks the arguments against patterns and delegates via dispatch table to specific sub implementations.

Maybe message the author?

HTH! :)

1) well I didn't spend much more guessing effort into this undocumented 0.02 version from MAR 26, 2005

2) well, it does prototype checks when compiling, but that's another thing
