Did I say perl?!

[nashdj]

System.out.print("Just another perl hacker?");

Just try it! :)

I can deconstruct this one.....

System() . out() . print ("Just another perl hacker?");

Very clever, though it doesn't stand a chance under use strict

Not quite. In fact perl -MO=Deparse will tell you what it was compiled into.

'Systemout' . print('Just another perl hacker?');

And -w would have given you a few answers:

Unquoted string "out" may clash with future reserved word.
Useless use of concatenation in void context.

Whereas use strict; misguided you by making reference to strict subs.

[blakem]

So is this one of those instance where perl will do different things based on what subs are defined?

When I try:

#!/usr/bin/perl -w
use strict;

sub System {
  print "System\n";
}

sub out {
  print "out\n";
}

System.out.print("Just another perl hacker?");

I get no errors and it prints both "System" and "out"....

Update:


#!/usr/bin/perl

# comment out these two lines to change meaning of construct in main
sub System { return "SystemSub " }
sub out { return "OutSub " };

my $val = main();
print "\n'$val'\n";

sub main {
  System.out.print("Just another perl hacker?");
}
