inner templates?

[dennis luehring]

hi

i've try to write an template wich calculates e

ok here it is - but wait i need a helper template to reduce the 
interface to my needs (just to adjust the precision) - is there any way 
getting rid of these helper template (maybe an inner-template or something)?

--
import std.stdio;

template e_help(double p, double s, double f, int n)
{
   static if( s > p )
     const e_help = e_help!(p, s/n,f+s/n,n+1);
   else
     const e_help = f;
}

// this is the interface i want - but without the e_help template
template e(double p = 1e-14)
{
   const e = e_help!(p, 1, 1, 1);
}

void main()
{
   writefln("e: ", e!());
}
