When reducing, we need to apply semantic function. However, the type of (any) semantic function cannot be recovered due to existential unpacking.

Good news:
I finally decide to spend some time and dive into LR parsing again. The result is we have a stackless LR(1) parser for grammar 4.55 in ASU86. The idea of course comes from Ralf Hinze's paper. This is particular cool because no explicit stack data structure is present now. The procedure of how to write such stackless parser is also clear to me.
Bad news:
