November 29, 2007 Function pointers/delegates  

 
real function(real x) y = function real(real x) { return sqrt( 1  x * x ); }; Is it just me or does it seem odd that real and function are swapped on one side? I can kind of see this if it's for singlepass parsing, but isn't there a better way? It's not intuitive at all.

Agreed I always get this wrong and has to correct compiler errors.

I like the way C# 3.0 does anonymous functions. I believe the idea comes from Nemerle. It would be something like: real function(real x) y = real <= (real x) { return sqrt(1  x*x); };

Same here.

I like the way D does anonymous delegates. <g>
real delegate(real x) y = (real x) { return 1  x * x; };
