It currently uses a stack bytecode machine by default, and it can
compile to two intermediate forms (PosLambda, which you don't want to
know any more about, and Yhc.Core, a simple and orthogonal IR designed
for use by external tools such as compiler backends)

Neil Mitchell is working on a ultra-optimizing C backend for Yhc.
Frankly this incongruity scares me.
