[julia-users] What's [] called? ie How do I refer to the array construction function?

[andrew cooke]

If I want to pass the function that constructs an array of Any, given some 
values, to another function, what do I use?

Here's an example that might make things clearer:

julia> f(x...) = Any[x...]
f (generic function with 1 method)

julia> apply(f, 1,2,3)
3-element Array{Any,1}:
 1
 2
 3

julia> apply(Any[], 1,2,3)
ERROR: MethodError: `call` has no method matching call(::Array{Any,1}, ::
Int64, ::Int64, ::Int64)
Closest candidates are:
  BoundsError(::Any...)
  TypeVar(::Any...)
  TypeConstructor(::Any...)
  ...
 in apply at deprecated.jl:116

where I am looking for what the built-in equivalent of f() is.

I may be even more confused, because I also don't understand why this fails:

julia> call(f, 1, 2)
ERROR: MethodError: `call` has no method matching call(::Function, ::Int64, 
::Int64)
Closest candidates are:
  BoundsError(::Any...)
  TypeVar(::Any...)
  TypeConstructor(::Any...)
  ...

So any guidance appreciated.

Thanks,
Andrew
