This feature was discussed several times in past for D. The
advantage is more readability for the code and less surprises.
The disadvantages are more typing, some code breakage of D2
code (because even if at the beginning it's a warning, and
later a deprecation, you will eventually need to enforce it
with an error).
Why make it a requirement or give a warning.
Just allow the programmer to do it in version 2.x or 3.x.
If it catches on, then start with a warning in version 4.x or
whatever.
Note: I would not add this feature if it creates a lot of work
for the compiler writers.
