How can that be?
Original expression:
_($"$foo")
Expands to:
_("%(x1)s"%{"x1": foo})
Standard Python order of operations will do the %-interpolation before
the method call! You say that it could instead be
_("%(x1)s")%{"x1": foo}
But how would Python know to do that? "_" is just another function.
There is nothing magical about it. What if the function was instead
re.compile? In that case I would want to do the interpolation *before*
the compilation, not after!
Are you saying that the "_" function should be made special and
recognized by the compiler?
