You're absolutely right.  It's not safe for me to do it now without
breaking binary compatibility, but I marked it on the TODO-list for a
next libtagcoll release.

In the meantime, the class is luckily very simple and you could just
copy and paste it changing the item type.

By the way, for a future libtagcoll I was planning to make it into a
static-only library, as it's mainly a bunch of useful classes without a
specific interface philosophy behind.  libdebtags or other libraries
would take from libtagcoll what's useful for their specific domain, fit
it into their API and shit the code into their static libraries.


Ciao,

Enrico
