I like dlang but i don't like dub
Dlang includes some good ideas. But dub pulls in so much stuff. Too much for me. I like things which are clean,lean,little,small. But when i use dub it links with so many libraries. Are they really needed ? And how do you compare to pythons pip. Feel free to elaborate.

Which is similar to what Java does. When i was first learning Java in a company i would make main() and have it run all the unittests of that particular module, then have a different file that actually combined all the tools together to run the program. Though when making the jar I'd specify which one actually was needed. But this was... 10 years ago.

If ```import std.regex;``` is commented out or if
```-checkaction=context``` is removed from the cmd line the
unittest passes. Can anybody reproduce this?

Hey everyone, I am in need of some help. I have written this

After some research about how to initialize immutable
associative arrays people suggested using `shared static
this()`. So far this worked for me, but I recently discovered
that DMD cannot compile this in release mode with
optimizations.
`dub build --build=release` or `dmd` with `-release -O` fails:
```
code windows949

function zencoding.windows949.table._sharedStaticCtor_L29_C1
dmd failed with exit code -11.
```
I usually compile my projects using LDC where this works fine,
but I don't want to force others to use LDC because of this
one problem.
Hence I'd like to ask on how to change the code so that it
compiles on DMD in release mode (with optimizations). I
thought about having a computational algorithm instead of an
encoding table but sadly I could not find any references in
that regard. Apparently encoding tables seem to be the
standard.
Why not use a simple static array (not an associative array).
Where the values are indexed on `key - min(keys)`. Even with
the holes in the keys (i.e. keys that do not have corresponding
values) it will be smaller that the constructed associative
array? The lookup is also faster.
