Compiled as in C/C++, so you want e.g. "GtkWidget *" for arguments of
type Gtk.Widget?  Reversing g-ir-scanner is easy for the basic cases,
but gets nontrivial with stuff like inout arrays.

You'll have to clarify exactly what you want to do with a string
representation.

Call g_base_info_get_interface() to get the target type, then
g_base_info_get_type() will tell you whether it's e.g. a
GI_INFO_TYPE_ENUM, a GI_INFO_TYPE_OBJECT, etc.

The gjs and pygobject git repositories should be useful references.
