I have a function which is suppose to take a variety of inputs, one of them
is an array of file names. The problem I'm running into is that sending in
an ASCII string array, Array{ASCIIString,1}, to a function with a more
general definition, Array{String,1}, it give me a method error.
julia> y = ["Hello","cruel","world"] 3-element Array{ASCIIString,1}:
"Hello"
"cruel"
"world"
julia> isa(y,Array{ASCIIString,1}) true
julia> isa(y,Array{String,1})
false
julia> isa(y[1],String) true
julia> isa(y[1],ASCIIString)
true
Why won't Array{ASCIIString,1} qualify as a Array{String,1}?
