WebDec 29, 2024 · 1. Any time a non-exact match is passed in for a function parameter, a conversion must be done. When you have two functions, regardless if one is deleted, they still participate in overload resolution. The compiler picks the best match, then either generates a call to it, or fails if the function is inaccessible or deleted.
