So in Ruby and R and Scheme and... I have happily used map /
collect for years and years.
Lovely thing.
So I did the dumb obvious of
string[] stringList = map!...;
And D barfed, wrong type, some evil voldemort thing again.
So..
auto stringList = map!....;
and we're good..
and happily use it as
foreach( s; stringList)....
Suddenly the words in the map! documentation made sense to me...
unlike Ruby, map doesn't allocate and populate an array. It just
returns a lazy range.
No array is allocated (unless I ask for one), it just does the
lambda when I want it in the foreach!
Cool! Very very cunning. Very light on resources.
I itch to get D working in the OpenEmbedded environment...
