in D std.conv.to allows universal type conversions, it's used very frequently and simplifies code a lot.

Is there anything similar in nim? if not could we add it?

import std.conv:to;
auto a1="123".to!int;
auto a2="123".to!double;
auto a3=123.to!string;
// custom conversion:
struct A{
  auto opCast(T) if(is(T==float) || is(T==double)) { return 1.0; }
}
auto a5=A.init.to!double;

Instead in nim I see parseInt, parseBool, etc which is:

• not as scalable (introduces tons of symbols)
• not as searcheable
• not as elegant as D's to.
• not generic (doesn't work in generic code)

proposed design:

see nim-lang/Nim#7488
