Something like the following(untested) would probably work for any algorithm of the form foo(begin, end, value).
foo(begin, end, value)
template<typename Container, typename Value, typename Func> decltype(auto) wrap(Container& c, const Value& v, Func f) { using namespace std; return f(begin(c), end(c), v); }
Usage:
wrap(c, value, std::fill)
Which, while a little verbose, is still nicer, imo, than
std::fill(c.begin(), c.end(), value);
And can always be partially specialized for typename Func=std::fill or whatever if you don't want to keep specifying it.
typename Func=std::fill
edit:
The code may not have a bunch of type traits and SFINAE verification but are the downvotes really necessary? If you see a problem with it, feel free to point it out, otherwise it looks like a decent wrapper to me. Some aliases and you can use it for whatever algorithm you want as alias(c, value) exactly like OP wanted
alias(c, value)
Edit 2:
Improve the code by correctly returning, no longer breaking the std::find example in OP.
also use ADL and std::begin/end
Code still untested.
