Like std::unary_function, the return type is the last parameter. It defaults to void, which preserves backwards compatibility, and also means that the most common case remains simple. I wanted to do this without losing performance on any platform. It turned out to be easy to do this for ...
STLstd::mapwill not be implemented in CTL because maps only provide slight syntactic improvements over sets. STL variants of multi-sets and multi-maps will not be implemented because similar behaviour can be implemented as an amalgamation of asetandlst. ...

double, whose values are elements of the double value set or, where supported, the double-extended-exponent value set, and whose default value is positive zero The values of the boolean type encode the truth values true and false, and the default value is false. The Java Virtual Machine...
NaNs are unordered, so numerical comparisons and tests for numerical equality have the value false if either or both of their operands are NaN. In particular, a test for numerical equality of a value against itself has the value false if and only if the value is NaN. A test for numerical...
