I'm working on a proxy contract that will perform calls as follows:
bool success;
bytes memory returndata;
(success, returndata) = _to.call.value(_value)(_data);
require(success);
this works great, except that, if the call reverts with an error message, this function will simply reverts, hiding the reason string.
How can I retrieve the reason string (I assume in the returndata) and use if to revert properly

It is simpler than you think:
require(success, string (returndata));
See documentation for details. You may also forward raw bytes, but you will need to use assembly.
I tryedrequire(success, returndata);
and started looking into assembly when it failled to compile ... thanks for proving how stupid I am :P
