in thread Unparseability is A Good Thing

Yet another proof:
BEGIN { my ($add_ts) = @ARGV; eval 'use subs qw( die )' if $add_ts; } sub die { my $ts = '[' . localtime() . '] '; my $msg = join '', @_; $msg =~ s/^/$ts/mg; CORE::die($msg); } die("foo\n");
>perl test.pl 1 [Sun Aug 23 11:52:55 2009] foo >perl test.pl 0 foo

Execution is required to decide whether die is a subroutine call or an operator.
