Hi Alex,
I think you're looking for join.
julia> join(1:10, " - ")
"1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10"
If you haven't tried it, :methodswith and :methods are both amazing command
line functions.
julia> methodswith(Array)
312-element Array{Method,1}:
*{T,S}(s::Base.LinAlg.SVDOperator{T,S}, v::Array{T,1}) at
linalg/arnoldi.jl:241
[lots of output -- can be used effectively if your terminal supports "find"]
julia> methods(join)
# 1 method for generic function "join":
join(args...) at strings/io.jl:104
Hope that helps,
David
