Ok, but then why does it return the Vector{Any}. The following two
functions give different results
function makestring(fun)
A::Array{ASCIIString} = [fun(i) for i = 1:3]
end
function makestring(fun)
A::Array{ASCIIString} = [fun(i) for i = 1:3]
convert(Array{ASCIIString},A)
end
I thought maybe it was a weird REPL thing, but it's not.
