according to the spec here: https://dlang.org/spec/expression.html#order-of-evaluation
++expr becomes ((expr) += 1)
expr++ becomes (ref T x){auto t = x; ++x; return t;}(expr)

Yet the PostExp is inheriting the binary expression while the preExp is inheriting the unary expression in the dmd source code.
Just what is going on here? Should it be preExp inheriting the Binary expression instead?
