in reply to variable function thingy

What you're looking for is a reference to a sub. You need something like this: 

$func_ref = \&post;    #this lets func_ref point at a sub call post

 ...

&$func_ref();          #call the sub we've pointed at

    This answer is correct, but I would also add that it is possible to store the subroutine name rather than as code reference. For example:

    sub test {
    print "Hello world!\n";
}

my $subroutine = "test";
&{$subroutine};

    The caveat to this approach is that it breaks strict refs unless the $subroutine scalar is evaluated (eg. eval $subroutine).

     

    Update - Check out the nifty example from broquaint in this thread here

     

    perl -e 'print+unpack("N",pack("B32","00000000000000000000000111010010")),"\n"'
