I'm guessing you mean plai-typed. This is a simple type-inferred
language designed for teaching.  Because the language is simpler, the
type inference is in some sense better; it requires less hints. On the
other hand it lacks some features of typed/racket, like occurrence

plai-typed (and plait, discussed below) also miss some of the "batteries
included" features of racket, like a rich set of looping constructs,
formatted output, and so on. I find students who know racket chafe a bit
at the minimalism of plai-typed / plait.

I would recommend looking at "plait", which is an actively maintained
successor to plai-typed, and works fine with Racket 7.5 (raco pkg
