Hmm, I wasn't able to implement such detection for a free function because function template don't have a type (only concrete instantiation do).
By wrapping the function inside a struct I can showcase what I was talking about (because now I can make a template that takes my struct as a parameter). godbolt.org/z/z5a1h6
All in all maybe this is not really a problem with free function but only with member function (static or not).
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
Thanks, I have corrected this mistake.
I completely understand the principle. But it is not clear to me how would you write such a code. Can you provide a basic example please?
