 I look at the context dependence/well defined token boundaries.

 Mostly do everything you can in the lexer. I did write a Fortran 77
that does mostly everything in the parser. Since fortran-like languages
have well defined keywords/delimiters.


 call xyz(5)= format(write(6,7))

 do 100 i=1.7


 good luck...

 if then then=else  else if else=then then then=else
