Resample indices are abstract types. This is bad for performance:

https://docs.julialang.org/en/v1/manual/performance-tips/#man-performance-abstract-container

Minimum working example:

bootstrapStatistic(
    [1.,2.,3.], 
    sum, 
    CBBsampler, 
    2, 
    5
)

Gives:

BlockBootstrap.bootstrapResult(6.0, [8.0, 9.0, 10.0, 9.0, 8.0], Array[Integer[1, 2, 2, 3], Integer[3, 1, 2, 3], Integer[2, 3, 2, 3], Integer[3, 1, 2, 3], Integer[3, 1, 3, 1]], Array[[1.0, 2.0, 2.0, 3.0], [3.0, 1.0, 2.0, 3.0], [2.0, 3.0, 2.0, 3.0], [3.0, 1.0, 2.0, 3.0], [3.0, 1.0, 3.0, 1.0]])
