It's essentially the same. I only suggested it because the
original question was about alternatives to pointers, and
`Nullable` isn't a pointer.
you are wrong, the question wasn't about "an alternative to
pointer"
i'll quote myself:
Is there a way to get the value instead of a pointer? while
keeping the conciseness (one line)
this is not asking for an "alternative"
if i have to call `.get` or dereference the pointer myself, the
premise of "conciseness and one liner" is lost
i pasted a simple example so everyone understands the task, my
actual use case is more complex and longer
I suppose it goes to show that avoiding language features just
for the sake of it ("no pointers", "no templates", "no
imports", ...) is unlikely to accomplish anything useful. :)
you didn't understand the question, so why assume this?
if checking for/getting a value from a hashmap requires all that
crap, then perhaps something is wrong with the language, and it
perhaps isn't the one i should have picked for the task
my mistake perhaps, not yours
besides, i do use the language features in my project, templates
and mixins to solve larger problems, it's great, and reason why i
picked D
another thing people don't understand:
```
$ time make build-game
real 0m0.402s
user 0m0.352s
sys 0m0.050s
```
i value this too, more than anything else, and i like good error
messages
i don't like cryptic error messages and 10+ seconds build times
i won't bother reading this thread, as i said, i lost interest,
if you can't understand what an improvement is from a user PoV,
then there is nothing else for me to say
