You're right. This is a bit advanced code sample, which uses
templates, template constraints, contract programming among
syntax advantages of D.
Hum it shows the power of D sure, but IMHO it also shows 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 for example:
real[d] bezier!(size_t d && d > 1, Number &&
isFloatingPoint!Number)(Number[d][] p, Number t)
or:
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
