Agreed. But the program flow would be such (pseudo-code):
(1) print STDOUT
print STDERR
(2) now print to both in one print statement
(3) now go back to
print STDOUT
print STDERR
I want to switch back-and-forth between being able to print to STDOUT, STDERR
with one 'print' statement and then back ...

Well it will, but there is no need to do that. You can print to
STDOUT and STDERR even while the tee exists.
print $tee "Foo\n";
will go to both
print STDOUT "Foo\n";
will go to STDOUT and
print STDERR "Foo\n";
to STDERR.
And
print "Foo\n";
to the select()ed filehandle.
