It's not that complex. Try to comment out most of the code and add some prints. IsType is a recursive template missing in Phobos2 too, it returns true if the first type is any of the following ones, you may remove it if you aren't able to write it.

I believe Tango has an extensive locale library which does this sort of thing.
