# . from gi.repository import foo [Unversioned requirement of 'foo']
# . from gi.repository import foo-1.0 [versioned requirement]
# . And we do not stumble over:
# from gi.repository import foo as _bar
# from gi.repository import foo, bar
# - in JS:
# . imports.gi.foo; [unversioned requirement of 'foo']
# . imports.gi.goo-1.0; [versioned requirement]
# . The imports can be listed on one line, and we catch them.
# Forms currently not detected:
# - js: imports.gi.versions.Gtk = '3.0';
# - py: gi.require_version('Gtk', '3.0')
