Actually, I looked into how Emacs handles implicit pushes, and found the
answer to *my* problem, not sure if the same is with yours. Emacs Calc
uses `unread-command-events` in order to perform the addition. That is,

1 1+
(space verbatim)
is read as:
1 1++
where the first + pushes into the Calc stack, and pushes "+" into the
command queue, for the Calc stack to process as addition.
