* Modifies #1100
* That PR comes from https://github.com/phlptp/CLI11 and unfortunately I
have no way of opening a PR to that repo, pointing to that branch...
The commit you care about is
9a2884ad6a
@phlptp
where I fix the build error on LLVM 19 with C++26 after rooting the
actual template issue (see
https://github.com/CLIUtils/CLI11/issues/1098#issuecomment-2572715578)
It comes down to C++26 adding a tuple interface to std::complex
