I wrote a LaTeX macro package for my university's PhD thesis format, and like a lot of such packages, the bulk of the work was in TeX rather than LaTeX. It's...well, I'm struggling to find the appropriate word that means "awful, but sort of comfortably awful." Like a lot of things, if you're handed a finished product, it looks like random noise. If you could watch it being written, it pretty much makes perfect sense. It's a hideous syntax, and sometimes I still wake up in a cold sweat with long strings of '#' signs running taunting me from the corner of my eyes. But I can't say it was all that daunting to write, although I suspect my TeX code was highly non-idiomatic.
