Hum it show the power of D sure, but IMHO it also show its syntax 
deficiencies..

For me this "real[d] bezier(size_t d, Number)(Number[d][] p, 
Number t)
    if(d > 1 && isFloatingPoint!Number)" is difficult to read, and 
a better syntax would be:
real[d] bezier!(size_t d && d > 1, Number && 
isFloatingPoint!Number)(Number[d][] p, Number t)
or maybe:
real[d] bezier!(size_t d, Number; d > 1 && 
isFloatingPoint!Number)(Number[d][] p, Number t)

The template parameter would be indicated in a !() (as in a 
call), and the template constraints inside the template 
parameter: this way the template parameters are clearly indicated 
and separated from the function parameter.
