just (re)reading *old* threads : is it possible to extend the perl sigil behaviour . that is , one day somebody decides it needs ¢ as sigil for certain class of variables . will it be possible to do . ( without rewriting the whole perl ) e.g. my ¢a = ... ; and this being the same as my ??a is Cent_sigil_type ; like my $a ; is same as my $a is Scalar ; ( as I understand , perl knows what to do with $a not because it notice every time '$' in the beginning but because it notice the compile -- time property of that variable "is Scalar" ) I am not sure if that is *all* sigil is about in perl but if yes then adding new sigil will be doable : just add one more property to all variables starting with ¢ , e.g. ( and provide corresponding functionality -- that is a black hole !) . so it seems that sigil *is* extensible. ( at least through some sort of filtering ) . e.g. I can force all variables starting with 'A' to be constant . now 'A' is special sigil . ( can I ??? ) ( probably this is something perl should avoid somehow ) arcadi .
