In python a common performance tip for joining many strings together is
to use the join method. So, for example, instead of
"a" + "b" + "c"
use
''.join(["a","b","c"]).
The idea is to avoid creating temporary objects that are immediately
thrown away. It's obviously overkill for such a small number of strings,
though.
Is there any equivalent method/advice when concatenating many strings
together in D?
There's std.algorithm.joiner[1] and std.array.join[2]. I don't know if
they're any more efficient than using "~". There's also
std.array.Appender[3] if you want to do a lot of appending and want the
most efficient way.
