I remember discussing here that "print FILEHANDLE" has a special magic different from normal "indirect object" syntax.

but the parsing of bar Foo +6; is not really as dangerous as print $x +6 is.

If Foo was a constant, any association to the package Foo would be overwritten.

  DB<140> package Foo; sub bar { print __PACKAGE__."::bar => [@_]\n"}
 
  DB<141> package main; sub bar { print __PACKAGE__."::bar => [@_]\n"}
 
  DB<142> bar Foo+6;
Foo::bar => [Foo 6]
 
  DB<143> use constant "Foo" =>5 
 
  DB<144> bar Foo+6;
main::bar => [11]

But in the OP $q doesn't hold a filehandle.

UPDATE: Maybe the whole confusion started, when variables for filehandles were introduced.
