Re^7: Perl precedence details

Seems there is no any list of named unary built-ins, except I found in the book

Sure there is :p its perlfunc, anything which takes at most one arg is unary

http://perl5.git.perl.org/perl.git/blob/HEAD:/t/op/cproto.t anything with "($)" or "(_)" or "(;$)" or "(_;$)" or "(;*)" or "(*)" or "(;+)" is unary

Yeah, it would be nice if there was a hash just saying this prototype stuff

Crap, some unaries has undef proto, like return. But anyway, this is really helpful.	[reply]

return isn't unary, it can take zero or more args ... I only see defined/delete/exists goto/last/redo, that are "unary", the rest like chomp/chop.. can all take more than one arg	[reply]

And (_;$) is not unary, two arguments	[reply]
