This Julia package implements a RunLengthArray{N,T} type that behaves like a
1D array but is extremely efficient if there are several repeating instances of
a few values, like in the following example:
using RunLengthArrays
x = RunLengthArray{Int,String}(["X", "X", "X", "X", "O", "O", "O", "O", "O"])More information is available in the documentation.
