Description

While calling methods with only positional arguments of different types is pretty easy (with tuples of IntoPy), for kwargs it gets complicated (see #1462).

Would it be useful to have a macro that can be used like so:

obj.call((pos_arg1, pos_arg2), kwargs! { key1=value1, key2=value2 })

Research direction

Start by reading issue #1462, which describes the current kwargs difficulty, then inspect the existing argument-conversion and macro entry points. Done means establishing whether the proposed kwargs! { key1=value1, key2=value2 } syntax is viable and documenting or testing the resulting call behavior.
