Re: local vs. $self-> pointer to subroutine

Perl has a special - widely unknown - syntax for this:

my $func_Ref = \&$self->isInst;
 
$self->$func_Ref( ... );

PS: But I'm not sure if the performance win does worth it. AFAIK Perl does a lot of optimization like method caching to speed things up.

UPDATE: typo fixed

What are the criteria for calling it wildly unknown, that you didn't know it? :)	[reply]

Hi BUK! Hi! I am not BUK, or a BUK. Simple! Practically nobody mentions it. Whether somebody mentions it, or you know about it, doesn't make it unknown, or wildly unknown Search the archives and prove me wrong... Like your link shows, the documentation mentions it, proof enough.	[reply]
