Would this mainly be used by

SSA seems to be something intended for compilers to use as an
intermediate representation, not something to actually write
code in. So I'm puzzle
dicts and lists will keep working as before. They will not support
keyword arguments (probably ever, as there is no clear semantic for
them) and the current implementation simply throws an error if the
user tries to.
Other classes will take advantage of the syntax for enhanced behavior.
