Christian, John,
thanks for your replies. Yes, that's what I am currently doing in my
plugin, and it's a very flexible solution, since the argument of
MyFunction does not have to be equal to the lhs.

I was just curious whether one could replace it with

imap <cr> <plug>(MyPlug)

where <plug>(MyPlug) maps to some function. In this case, you cannot
pass arguments, so I was wondering whether one could access the lhs of
the mapping through the plug (presumably, via some special variable).
I couldn't find any way, but I wanted to make sure I wasn't missing
anything from the documentation.

To be clear, this is not a feature request: the "typical workaround", as
I've said, is just fine.

Thanks again,
Life.
