Hello !

I'm afraid there's something wrong in the goto parsing of Perl.
Please kindly confirm.

When I run the program below;

	#! /bin/perl -w
	# gotoTest.pl

	goto FIN if 1;

	print "skipped \n";
	&sub_routine;

	FIN:

	sub sub_routine {
		print "skipped 2\n";
	}

The error returns;

	C:\>gotoTest.pl
	syntax error at C:\gotoTest.pl line 11, near "sub sub_routine "
	Execution of C:\gotoTest.pl aborted due to compilation errors.

If I corrected the program as;

	#! /bin/perl -w
	# gotoTest.pl

	goto FIN if 1;

	print "skipped \n";
	&sub_routine;

	sub sub_routine {
		print "skipped 2\n";
	}

	FIN:

It runs safely.

If I corrected the program as;

	#! /bin/perl -w
	# gotoTest.pl

	goto FIN if 1;

	print "skipped \n";
	&sub_routine;

	FIN:
	;

	sub sub_routine {
		print "skipped 2\n";
	}

It runs safely too.

Thank you very much !
