Improved and configurable drop-in replacement to std::function that supports move only types, multiple overloads and more
Starting with Visual Studio 2022 (17.3.0) the following warning is emitted: ``` include\function2\function2.hpp(1176): warning C4305: '': truncation from 'bool (__cdecl *)(void)' to 'bool' ``` Neither `bool(callable)` (as it was written),...

@Naios Here are some suggestions about `fu2::function_base`. 1. There are too many boolean template parameters. It's hard to imagine what specific combination of policies are given if we just write...
@Naios Suggestion For example, ``` using MyFunction = fu2::function_base; auto cb = [foo, bar] {}; static_assert(MyFunction::is_inplace(cb), "Lambda too big!") ``` This could be useful to maintain code over time and...
@Naios Being able to construct an object rather than having to copy/move one in would be very useful, particularly for objects that may be expensive to construct, or (for unique_function)...
@Naios This is relatively minor, but I thought I'd mention it before I forget about them: building `function2` strictly as a copied header with `clang` can trigger a few warnings,...
@Naios ----- ### Commit Hash e3695b4b4fa3c672e25c6462d7900f8d2417a417 ### Expected Behavior When trying to make a fu2::function with a move-only object, you get an assert_error with the message "Can't wrap a non...
@Naios ----- ### Commit Hash Git Tag 3.1.0 ### Expected Behavior As Rvalue functions are meant to be single shot functions, the second invocation should result in raising a bad_function_call...
@Naios ----- ### Expected Behavior The const-ness of the callable should be propagated to the erased function pointer ### Actual Behavior ``` In file included from main.cpp:1:0: function2.hpp: In instantiation...
@Naios Great improvement over std::function, but there is no [std::function::target](http://www.cplusplus.com/reference/functional/function/target/) counterpart. I use it for logging addresses of underlying callable objects, very useful for debugging: ```c++ ... catch (const std::exception...
