BTW, I never understood the usefulness of Statement Modifiers.
Even reading the examples in perlsyn.pod:

    print "Basset hounds got long ears" if length $ear >= 10;
    go_outside() and play() unless $is_raining;

seeing "do these things" upfront and then realize "ah, but that
is done only when this holds true", interrupts the flow of
understanding while reading a program by somebody else [*1*].
It is worse if the Statement Modifier is a loop control.

(flamebait) Compound Statements take BLOCK and people who want
to do a one-liner could not do so without braces.  I've always
thought Statement Modifies as a lame workaround for that
problem.

[Footnote]

*1* This is true even for me; my mother language is Japanese,
which tends to hang negation at the tail of the sentence, and
double negation is not unusual.  This makes it impossible to
know what a sentence states before reading it to the end, so I
am used to that "coming back to the main part after reading
through the sentence", but I do not welcome that when I am
reading programs.
