[julia-users] Types that behave like functions: can I define f(x) using something like getindex

[Ed Scheinerman]

I'm working on a type that will have a function-like behavior, so I'd like 
to write f(x) to evaluate the function f at x. I could define 
getindex(f::MyType,x::Number) so f[x] would behave as desired, but it would 
be aesthetically pleasing to be able to type f(x) in this case. Is there a 
way to have something like a "function_call" I could define to make this 
happen? Or perhaps this already exists in Julia and I just can't find it.
