[boost] enable_if and non-template member functions?

Folks, I have a problem with enable_if:  it works just dandy for template 
member functions in my class, but I have some *non-template* member 
functions and constructors that I want to enable only if the template is 
instantiated with template args that meet certain criteria.  Seems like I 
can't do this with enable_if as it then generates an invalid class 
definition.  I guess I could use base classes, and/or partial 
specialization, but both involve a lot of code duplication I'd rather not 
have.  Anyone any ideas?

Thanks, John.
