in thread Is space supposed to be ignored between a sigil and its variable name?

What do those print, and why?  (Without cheating and running the code! :) 

#!/usr/bin/perl

$foo = "foo";

print "1: $ $ $ foo\n";
print "2: $ $$ foo\n";
print "3: $ $$foo\n";
print "4: $$$foo\n";

    Excellent exercise :D

    Okay, okay, I admit it - I got 1 right, but the other 3 flummoxed me, so I ... well I cheated!!

    Now I know what they all print - all that's left to do now is the hard part i.e. RTFM & work out why ...

    A user level that continues to overstate my experience :-))
