Now consider the less well known language PL/I, with a much
fancier preprocessor. The PL/I preprocessor allows preprocessor
procedures, and procedure calls.

You mean like:


#define BEGIN {
#define END }


I have seen faux-Pascal before, but not faux-Algol.

[The faux Algol-68 was pretty amazing. For that matter, so was the
PL/I preprocessor, which let you write entire programs that run at
