I keep hearing how const is nigh unusable in D, and except for ranges
I litter my code with const everywhere, pretty much just as often as I
used in C++.
I once spent a good amount of effort to annotate my code with pure and
inout only to find a compiler bug, then I realized that annotations
aren't really needed, because the collection is inherently mutable
anyway (appender).
I use const all over the place too. And I made PR to other libraries to
add const qualifier.
Yes, it sometimes forces me to make a copy of data to mutate it - but
I'm pretty sure this is the purpose of the qualifier. This helps me to
catch/prevent bug. So I don't agree with people who do not use const at
all. Definitely const qualifier in D is usable and is useful. The same I
can say about properties - for example I use them in meta programming to
detect what to serialize/process - I skip methods but serialize
properties and for me this is a nice language feature.
