Every time I think I understand D, I don't.
Cool useful library functions like sumElement that magically
don't work on static arrays.
'private' is per module, not per class, making it pretty much
useless for preventing incorrect access and using .
completely different semantics for a class vs a struct. Is it a
reference? Is it a value? Look up the entire declaration and have
the entire Dlang manual open to find out.
As far as I remember, no automatic RAII support, even though it's
insanely useful. You have to manually write scope(end) stuff
which means any person forgetting one is now leaking memory.
Writing output in a deconstuctor (for learning) works. But then
you accidentally combine two strings inside it and the garbage
collecter crashes without a stack trace.
Documentation. Documentation. Documentation.
I just realized foreach copies by value by default. Maybe.
Sometimes. When? I don't even know anymore. Because I "thought" I
had to use foreach(ref) to be able to affect the original data
structure (because by value means its a copy, right?). Except
somehow everything has been working just fine, mutating the
original structure/array from inside foreach and adding
foreach(ref) makes no changes. Will it be faster? Maybe... who
knows.
And I really like D! But there's lots of "WTF" moments. There's
so much I have to Google for a single forum post with dead links
from 2014 which is only 30% like my use-case that describes my
error or problem.
