Since D strings are immutable (like in most other languages),
string concatenation is usually pretty inefficient due to the
need to create a new copy of the string every time.
I presume string concatenation using the typical array syntax can
be optimized by the compiler to do all of this in one shot, e..g
string newString = string1 ~ string2 ~ string3;
but what happens if I need to concatenante a large string in a
loop?
I tried looking through Phobos for a StringBuilder class (since
that is the common solution in Java and C#), but did not find
anything similar.
What is the D way of doing efficient string concatenation
(especially if it spans multiple statements, e.g. while in a
loop)?
