Re: How to bring in multimethods

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 š but since Perl doesn't do any static parameter checks when calling a sub˛, 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

Logic No¹⁾ I just want to write `frobnicate($object)` and not `Methods::frobnicate($object)`. With `use Exporter qw(import); our @EXPORT_OK =qw(frobnicate);` and `use Methods qw(frobnicate);` only one frobnicate is found²⁾ and with `Methods->frobnicate()` nothings happens. ¹⁾ I could read the sources for this (could take a while ;-). ²⁾ This yields "Logic::Easy multi dispatch failed" from Logic::Easy line 94.
