Is perl 4.0 going to have multi-dimensional arrays in the language? This is the only thing I haven't seen a good general-purpose perlish way of doing. Recently, I've wished for them several times, and ended up kludging around the problem. And they were ugly kludges :-) Marc

Actually, if Perl 4.0 is going to have new features, I'd vote for structures over multidimensional arrays. Right now, there are kluges and hacks using strings with pack() and unpack() to convert binary structures to and from the system libraries and calls. With structures added (using an appropriate syntax), such contrivances would no longer be needed. Just allowing array elements to have non-scalar values would be a good start. Not that having Perl up to this point hasn't been a Good Thing... :^) Alan Stebbens <hub.ucsb.edu> -- Alan Stebbens <aks@hub.ucsb.edu>

Recursive types. Yeah! See below. More to come...
split(/([ae])/,"ck.\narl her penotha");grep(eval'@z'.++$z.'=split(/z*/);
$_=*z'.$z,@_);for(reverse@_){*_=$_;print@_;}

How the heck does one use the patches to perl4.0, when perl4.0 hasn't been posted to the net (or if it was... were not any of the "normal" places)? Isn't this kinda getting the cart before the horse? -- Joe Garvey uucp: sumax!quick!johnny5!garvey J5 Research map entries are wrong for johnny5. They're Bothell, Wa. being fixed.

Just get the file perl-4.003.tar.Z from prep.ai.mit.edu. in the directory /pub/gnu and you don't have to patch at all. >Isn't this kinda getting the cart before the horse? Seems so.
