That's my view too, based on the days when I taught compiler writing.
Lexis and syntax is much the easiest part, and there's no need to make
a meal of it.  The least easy part is error detection, reporting and
recovery, and I think however much time you allocate to lexis and
syntax, at least half should be spent on that aspect.
