hm yes, it is somewhat inconsistent to have the tlp initialisation to take a
default value while normally that isn't the case.
have added \tlp_new:N (which is equiv to \tlp_new:Nn #1 {} )

that could only be done if you know that \prop_gput:Noo expand its argument
internally due to its implementation and you use this fact. so you use a
feature of the implementation which may not be there tomorrow
just assume for a moment we would built in checks for variables to be checked
for type or local global state then passing "\l_tmp_tlp" would fail on both
accounts (not that i propose that)
