These don't mix with the old syntax, right? Oh, if you remove your redefinition of \bool_if_p:n then they can intermingle.

The same benchmark I gave earlier gives two more numbers for a single loop over that somewhat complex boolean expression: one with the simplified \bool_if_p:n and one with the more complex implementation of \bool_if_p:n in the current code.

Original: 76Ás (using infix notation)
Current:  55Ás (using functional notation but the current \bool_if_p:n)
Simple:   35Ás (using functional notation with simplified \bool_if_p:n)

I'm not willing to throw away the infix notation, but I think it's worth adding (or, I guess, re-adding) the functional notation for those who want it.
