At least I could find a grammar in BNF, by following the links in
Wikipedia to <teampli.net/XPL/ldindex.html>.
If I had to write an XPL compiler, as an excercise, I'd try to handcraft
an LL(1) top-down parser for it. This approach will give more insight
into "how to write a compiler", than understanding how to use a compiler
generator. Finally that compiler can be rewritten in XPL. Much time will
have to be spent in implementing the system library (Implicit
Declarations) and memory management.
[It does depend on whether you want to write a modern compiler or one that
someone might have written back when XPL was new. -John]
