it depends! ;-)

sub ONE { "@_ \n Space doesn't matter! \n" }

print ONE ( TWO );          # sub-call

ALSO:

> perl
open ONE, ">", "/tmp/tst";

print (ONE (TWO));          # filehandle

__END__

BUT:

> perl
open ONE, ">", "/tmp/tst";

print ONE(TWO);             # sub-call

__END__
Undefined subroutine &main::ONE called at - line 3.
