XS vc Inline

[Robert H]

When would you not use Inline instead of doing it with XS? For example, 
I am thinking about doing a wrapper for Metakit (ie DBD::Metakit). I 
talked with the author of Metakit and he said he tried to do a Perl 
wrapper in XS once but got lost. Is it feasible to do something like 
that using Inline instead or would XS be the best case scenario for a 
DBD module?
