How does one remove that instance 'i'?
What exactly do you want to remove? After a[]=i your array
contain a lot of references to 'i'.
I would like to know how works: removing
- the first
- and all
references to 'i' inside the 'q'.
Perhaps, for all references to i it should look like:
a = a.filter!(a => a !is i).array;
Thank you! :)
But why a containers so complicated in D?
In C# I would go for a generic List<T>, which would support
structs and classes, where I simply could call '.Remove(T item)'
or '.RemoveAt(int index)'. I would know how this works, because
the method names make sense, the docs are straight forward.
Here in D everything looks like climbing mount everest. When you
ask how to use D's containers you are recommended to use dynamic
arrays instead. When you look at the docs for std.algorithm, e.g.
the .remove section, you get bombed with things like
'SwapStrategy.unstable', asserts and tuples, but you aren't told
how to simply remove 1 specific element.
