This check bails before it gets to the variant handling check:

if (td->fieldType != FIELD_FLOAT
	&& td->fieldType != FIELD_TIME)
{
	return pContext->ThrowNativeError("Data field %s is not a float (%d != [%d,%d])", 
		prop,
		td->fieldType,
		FIELD_FLOAT,
		FIELD_TIME);
}

Apparently it is possible to add Python modules to the game with the modloader. Unfortunately there is no documentation about the api.

nyan should provide a file api that we can inherit from.

Then we can natively interface to the openage file abstraction and do not need to read the whole file in the engine. Basically a class nyan::Filesystem that is specialized by openage. Ideally, the returned file lazily accesses all data through openage::util::File.
