>Description:
// I cannot see a problem with the syntax of the following 
// fragment; shouldn't one be able to overload template and 
// non-template functions in class scopes and be able to declare 
// them out of line?  From the examples in Sec. 14 of the standard
// my guess is that the fragment below uses the syntax intended for 
// this purpose. EDG compilers treat this fragment as I expect (the 
// executable returns 0 to the environent)

// the _inline_ definition of the functions IN the class 
// body works as expected
