The point of my answer is that I think the problem raised by Walter can't be solved by Phobos/dmd developers. And at the current state of D development trying to solve it will cause more problems (and more wasted efforts) than it can solve.

There's a pull in need of some love, I'd like to see this in D:
https://github.com/D-Programming-Language/dmd/pull/3615

Yes, it can be.

It's a pretty small program, 5000 lines.

1. renaming things to the latest fashion is an illusion of progress, not actual progress, such as fnmatch => globMatch

2. deprecated aliases to the old names can be kept for a long time without causing problems

3. when removed entirely, the documentation for them should be kept along with instructions on corrective action

This is more of an Ubuntu-y issue, but I'm having trouble getting it to link with ncurses. This used to work:

cc $(LDFLG)  -o med $(OBJ) -l :libncurses.so.5 -l phobos2 -l pthread -l m

but alas, no longer with the latest Ubuntu. (Linux people keep trying to get rid of termcap, it's a constant issue.) -lncurses fails, everything I try fails.

Any ideas?

A solution is to leave @deprected stuff for 2-5 years in Phobos (but in few cases this is not enough, because some names have changed purpose and signature).

You are wrong. Having good function names is extremely important. Renaming badly named things with more clear and more meaningful names reduces pain for both old and new users, reduces coding time, and in some cases even avoids some troubles.

This is usually true, but not always (see above).

I agree.

Hmm. Did you install libncurses5-dev (or libncursesw5-dev)? If not, try
`apt-get install libncurses5-dev` (or libncursesw5-dev as appropriate).
Otherwise, try -lncurses5 or -lncursesw5, perhaps?

I'd like to see this in D too. AFAICT, everybody else has approved it, it's just Walter who has some reservations about it.

What kind of cosmetic changes are needed?
