Your idea looks _much_ better from code clarity point of view, but it's
unclear to me, how to deal with it internally and in error messages. I'm
not a compiler guy, though.
Worse, it does not allow to set up fixity relative to operator that is
not in scope and it will create unnecessary
During development some toy base library I found impossible to use
Numeric literals. Quick search showed, that one need both fromInteger in
scope (reasonable) and, as I understand, access to Integer type from
'base' package ('base' for clarity later). It is perfectly reasonable if

In any case why can't the install syntax be
