--- Comment #2 from Agner Fog <agner at agner dot org> ---
Thank you Jonathan.
The problem is that the C++ standard is becoming so complicated that nobody can
master it, not even the persons who wrote the example in the proposal.
`_Float16 A{1.0};` gives a warning, which apparently is wrong.
`_Float16 A = 1;` gives no warning.
`_Float16 A = 1.5f16;` gives no warning, but I am not sure the f16 suffix is
supported by all compilers
