I find other functions/macros work just fine except take-like functions.

By the way, what is the @nobrace like macro?

[MikeInnes]

I'm not seeing this myself. Have you imported any other packages before Lazy.jl?

By the way, what is the @nobrace like macro?

Can you clarify? Happy to help out but I'm not sure I understand your question here.

[eccstartup]

I reply the second question first. I mean a macro that removes brackets. This is discussed here.

For the first one, I didn't import anything.

Regarding the deprecation warnings, I see them in IJulia but not in the REPL. I'm on Julia Version 0.3.7-pre+19 Commit e3fbe7e (2015-03-10 07:59 UTC)

@one-more-minute, I believe I'm also seeing this. I'm using Julia 0.4.1. Starting a new REPL session,

I installed Lazy with Pkg.add("Lazy"). I have no ~/.juliarc.jl file.

[boathit]

@xanderdunn you have to use like Lazy.take(20, fibs) see this thread https://github.com/one-more-minute/Lazy.jl/issues/27

[xanderdunn]

@boathit Thanks. You can see above I did actually try Lazy.take(), but I still got an error. I incorrectly assumed it was an error internal to Lazy.take, but actually I just needed to revise my fibs definition to use Lazy.drop as well.
