Re: [julia-users] delayed evaluation without a macro

[Tamas Papp]

Of course. Eg

delayed1 = function() 
 print("evaluating!\n") 42 
end  force(f::Function) = f()  force(delayed1)

You just need the macros for the syntactic sugar, bookkeeping, 
etc.

Any intermediate Scheme textbook provides a lot of examples on how 
to do these things with closures.  

I am curious why you want to do it without macros, though; you 
just get a lot of boilerplate code. BTW, there aren't a lot of 
macros in Lazy.jl either. 

Best,

Hello,

I am interested in the delayed evaluation implementations like 
Lazy.jl  (one-more-minute) and LazySequences.jl (dcjones).  Both 
of these use  Julia's macros facilities.

Is it possible to implement delayed evaluation without using 
macros?

Thanks for any leads or good references on this.
