version 0.002; 2007-01-25

  * add is_pure_string() and is_pure_number() functions that determine
    how complicated a string scalar is

  * in documentation for is_number(), reference Scalar::Number and
    Data::Integer

  * correct version requirement of Scalar::Util in module, making it
    consistent with the dependency listed in Makefile.PL

version 0.001; 2006-08-03

  * bugfix: in is_number(), check whether numeric conversion warns, rather
    than using looks_like_number(), to avoid being confused by dualvars

  * in t/ref.t, skip *foo{FORMAT} tests on older Perls that don't provide
    that facility

  * refer to Data::Float for classification of floating point values

  * versioned dependencies in .pm

  * declare module dependencies in Makefile.PL

  * correct .cvsignore (had copy&modify detritus)
