[BUG] cppfront fails on valid cpp1 syntax for importing module partitions

[farmerpiki]

trafficstars

module;

export module utils:part2; import :part1;

results in part2.cpp2(4,1): error: a namespace-scope object must have an initializer

there currently is a workaround, explicitly writing, but that might result in duplicate exports if it's needed in multiple places export import :part1;
