The C<if> and C<unless> modifiers have the expected semantics,
-presuming you're a speaker of English. The C<while> and C<until>
-modifiers also have the usual "while loop" semantics (conditional
-evaluated first), except when applied to a do-BLOCK (or to the
-now-deprecated do-SUBROUTINE statement), in which case the block
-executes once before the conditional is evaluated. This is so that you
-can write loops like:
+presuming you're a speaker of English. The C<foreach> modifier is an
+iterator: For each value in EXPR, it aliases $_ to the value and
