Good question. I haven't thought about it before you asked. For the moment I
don't know anything about limitations of particular compilers, but the
standard's appendix B - 'Implementation quantities' suggests '17' for the
'Recursively nested template instantiations'. But 'these quantities are only
guidelines and do not determine compliance.'
Any real-world data?
