This is going to make finding syntax errors a bit difficult, as many
will simply become concatination operators. Consider....
print "Foo"
foo("bar");
Did the author forget a semi-colon, or did they intend to concatinate
there? Also, consider this...
print foo "bar";
Is that 'print foo("bar");' or 'print foo()."bar";' in Perl 5?

Nathan finishes loading his gun. ;)
