sometimes GiNaCs templates are a mystery to me. In container.h there is the code
template<template<classT, class= std::allocator<T>> classC> container<C> & container<C>::prepend(constex & b) { ensure_if_modifiable(); this->seq.push_front(b); return*this; }
but AFAIK the STL does not have any push_front() method. And GiNaC does not seem to define it either. How can this work?
Same applies for pop_front() and sort()
voidsort_(std::input_iterator_tag) { this->seq.sort(ex_is_less()); }
Well, not every STL container provides every possible method. But the standard does require the ones you mention for the instantiated template classes. Check again! -richy. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>
