I think B::Deparse gets it wrong -- as it sometimes does -- when you add -p:

<Reveal this spoiler or all spoilers in this node or all in this thread>

This is confirmed by the more low-level output of B::Concise:

<Reveal this spoiler>

      I can't test ATM

      You gotta stop saying that :)

      Contrary to AnoMonk I doubt space matters.

      Sure it does, it matters how Deparse places the space, because it matters to perl

      <Reveal this spoiler or all in this thread>
      That is exactly as deparsed with -p, behaves exactly like the original

        it depends! ;-)

        > > most likely it depends if a function is known at compile time

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

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

print ONE ( TWO );          # sub-call

__END__
TWO 
 Space doesn't matter!

        ALSO:

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.
