Odd type bug (?) related to new call syntax

[timholy]

I haven't followed this carefully enough to know whether this is something I need to change in my code, or whether it's a bug in julia, but my preliminary investigation suggests the latter. Problem was initially reported by PkgEvaluator, timholy/Grid.jl#51. The error message seems quite strange: in this line, y should be a Vector, not an InterpGrid{Float64,1,BCreflect,InterpNearest}. Moreover, those same lines work fine when run at the REPL:

julia> ig = InterpGrid(A, BCreflect, InterpNearest)
4-element InterpGrid{Float64,1,BCreflect,InterpNearest}:
 1.0
 2.0
 3.0
 4.0

julia> y = ig[-3:8]
12-element Array{Float64,1}:
 4.0
 3.0
 2.0
 1.0
 1.0
 2.0
 3.0
 4.0
 4.0
 3.0
 2.0
 1.0

julia> @assert all(abs(y-A[[4:-1:1,1:4,4:-1:1]]) .< EPS)

julia>

Once it runs successfully this way, Grid's tests pass henceforth. However, if I just repeatedly say include("runtests.jl"), then it doesn't get to the point of running correctly.

git bisect identifies 39dfd92 as the first bad commit.
