You do realize, of course, that if you reverse these statements and
put the if and while at the end, then you don't need the parens:
print $x if $x > 10;
print $i while $i < 10;
(Although the latter is an infinite loop if $i < 10.)

I won't, but I will refer you to perldoc perlsyn, particularly the
section on "Simple statements".
