Next iteration:
[x; 2 * x; iota(10); x & 1]
If you don't like the syntax I've shown with foreach, then use the
Python syntax, it's readable and short and good:
[2 * x for x in iota(10) if x & 1]
Or:
[2 * x for x in 0 .. 10 if x & 1]
I feel it is too much a departure from the style otherwise present in D.
It is
important not only that the syntax is good in and of itself, but also in
the
context of D.
I agree with Simen. Use semicolons where you separate logical parts of the
expression like in for(each) and commas when you have an argument list or
enumerations where all elements have the same context or meaning (hard to
explain). So the Python syntax is [<calculation> for <counter> in <range>
if <filter>]. I don't know if the filter is actually required, but it
sounds like a neat idea. How about multidimensional arrays though?
