On of the earlier languages I knew, and maybe still favorite, is PL/I.

PL/I does have a powerful preprocessor, though I don't know so many
actually using its power.   It even has preprocessor procedures, if you
need them.

The most use of the power I have seen, is one for unrolling DO loops,
which unrolls smaller loops, but not larger ones, with either a
preprocessor %DO, or a real DO.

I do remember, though, first knowing abuot no preprocessor in Java,
and the trend of PL/I to C to Java, in decreasing preprocessor power.

in it, either. -John]
