Take a look at some of the modern stack processors (RTX, SC32).  There's no
pipelining; it's not needed.  They do multiple operations per clock cycle by
having multiple data paths.  One instruction can affect the data stack, the
return stack, memory, and I'd have to dig out my data sheets to find out what
else.  The RTX can do five operation in one clock cycle.

You have to consider stack machines according to their own strengths, not how
well or not well they handle non-stack language programming techniques.
