[julia-users] Call overloading and @code_... macros

[Luthaf]

The @code_llvm, @code_native and @code_lowered macros (but not the 
@code_typed) macro behavior does not feels right with the call 
overloading syntax:

julia> type Foo end
julia> Base.call(::Foo, x) = x + 4
call (generic function with 891 methods)

julia> f = Foo()
Foo()

julia> @code_llvm f(3)
ERROR: MethodError: `code_llvm` has no method matching code_llvm(::Foo, 
::Type{(Int64,)})
Closest candidates are:
  code_llvm(::Function, ::(Type{T<:Top}...,))

 in __text at no file (repeats 3 times)

I know I can use the call(::Foo, x) form, but this fails with the 
@code_native macro :

julia> @code_llvm call(f, 3)

define i64 @julia_call_43695(%jl_value_t*, i64) {
top:
  %2 = add i64 %1, 4, !dbg !8
  ret i64 %2, !dbg !8
}

julia> @code_native call(f, 3)

    push    rbp
    push    rbp
    push    rbp

Is this an issue, or is this the intended behavior ?
