  LaTeX evidently has a syntax based on Pascal, but this syntax is not
  explicitly part of LaTeX, only something that the developers of LaTeX use
  internally

I think you are probably referring to the pascal-ish comments that were
in the sorces for latex209 and some remain in the `oldcomments' sections
in the current sources. Leslie Lamport used those while designing the
original latex algorithms but they are not really used now. Most of them
have been removed as they had (even in the days of 2.09) got out of sync
with the actual code implementation and so were more confusing than
helpful.
