There's no user cost if they don't use Regex other then processing of a few extra includes on compile.
That's in a perfect world. On this planet, your library could not compile because a compiler bug prevents it to compile the regex headers, even if you don't use them.
Speaking about Regex: it fails only on few systems older: http://engineering.meta-comm.com/boost-regression/CVS-RC_1_33_0/user/regex.h... Format, by virtue of age is somewhat better: http://engineering.meta-comm.com/boost-regression/CVS-RC_1_33_0/user/format.... String algos ignore VC6 but otherwise work almost everywhere: http://engineering.meta-comm.com/boost-regression/CVS-RC_1_33_0/user/algorit... The combination of these libraries could reveal hidden flaws, though. /Pavel
