Depends on how far back in history you go.  I have seen quite a few
puzzled questions by people new to Forth who were confused why
something like
 
1.23 4.56 f+ f.
 
does not work as they expect. 

And there's never been enough support standard-wise to make that work.

This problem is increased by the
requirement in the standard that
 
123e f.
 
prints "123." (maybe with trailing zeros) rather than something that,
when copied and pasted as Forth input, reproduces that number.

Ditto.  The only person I'm aware to consistently raise the copy/paste
issue is you.  Mitch Bradley is a fan of parsing words like F# 123 but
he got no support.  Folks wanted the interpreter to expressly handle
floats hence the 'E' syntax.  Can't please everyone?
