How do I get the * glob, what is $*, and what is *{''}?

entropy has asked for the wisdom of the Perl Monks concerning the following question:

$a=*{}; # doesn't like that $a=*{''}; # that seems like a completely different glob! $a=*; # oops! - the * eats the ; $a=(*); # doesn't like that either

    $a = **;

    $* is a deprecated variable used for regexes.

      Wow, that clears it up.
      I had done '$a=*' in the debugger, which causes 'print $a' to show it as a glob (*main::;). I suppose the trick is that the debugger took it upon itself to add a couple of semi-colons in there, making it '$a=*;;' or in other words '$a=*{";"};'.

[Discipulus]: and anyway we have CB where every (democratic) opinion can be expressed
erix eat the rich!
[1nickt]: I do think it is sad that roho has received 3 downvotes for his polite request, as did I when I objected to the profanity in stonecolddevin's sig. I upvoted both him and Karl for the discussion. Way too much downvoting for inappropriate reasons here!
Discipulus learn that 'argue' has a little negative sense, he thought was a neutral sense, 'vox media'
[1nickt]: argue == discuss && argue == be contentious
[Discipulus]: you are right 1nickt i didnt voted nor downvoted; I just upvote perl content i like
[1nickt]: In Spanish, to argue (like a fight) is discutir -- does not mean to discuss !
[1nickt]: Sigh, this is why I gave up human-only languages and became a Perl linguist :-)
[Discipulus]: i just, rarely, downvote unpolite posts and spam, and wrong advices
[Discipulus]: discutere in eatalian is neutral: but discutere with wife sounds implicitly negative..
