I experimented with using the character 'ħ' in a variable name,

What did surprise me is that I still got a compile error even 
when the character was in a comment. Is there any way to make dmd 
not get fussy about unicode?

Oh, don't mind me. Turns out the problem was nothing to do with 
'ħ', somehow a '-' that wasn't actually a '-' found its way into 
my code and was confusing my numeric literals. All is well here.

Hmmm it's strange: I think d should support unicode on both 
comment and vars name.

This code works for me ;)

float distance(T)(T from, T to)
       {
          import std.math;

          auto toRadians = (float dec) => dec/180.0f*PI;

          auto R = 6371;
          auto φ1 = toRadians(from.lat);
          auto φ2 = toRadians(to.lat);
          auto Δφ = toRadians(to.lat-from.lat);
          auto Δλ = toRadians(to.lng-from.lng);

          float a = sin(Δφ/2) * sin(Δφ/2) + cos(φ1) * cos(φ2) * 
sin(Δλ/2) * sin(Δλ/2);
          float c = 2 * atan2(sqrt(a), sqrt(1-a));

          return R * c;

       }

What compiler version do you use?

I tried to compile your code on dpaste (2.070.0) and got this:

Oh, I see.

Is there any place where one can report bugs on dpaste?
