Preprocessed source

When porting code to use the new `deduced this` feature, I forgot to switch
`operator()` to `obj()` and got an ICE. Note that this happens even if
`operator()` takes no additional arguments.

Output of gcc --version:
gcc-14 (Homebrew GCC 14.1.0) 14.1.0

However, this also happens on online compilers when compiling for x86_64.
