Julia implementation Fortran-like array with arbitrary starting indices, negative or zero. Incurs a reasonable overhead vs. Base.Array, expected performance degradation should be strictly less than 2x.
# Fortran-like array with arbitrary starting indices
#
# usage:
#
# julia> include("FArray.jl")
# size (generic function with 51 methods)
#
# julia> y = FArray(Float64, -1:1, -7:7, -128:512, -5:5, -1:1, -3:3, -2:2, -1:1);
#
# julia> y[-1,-7,-128,-5,-1,-3,-2,-1] = 14

High Performance Streaming Analytics in Julia
# This code is part of a presentation on streaming analytics in Julia
# It was inspired by a number of individuals and makes use of some of their ideas
# 1. FastML.com got me thinking about inline processing after
# reading his great Vowpal Wabbit posts
# 2. John Lanford and his fantastic Vowpal Wabbit library.
# Check out his NYU video course to learn more (see below)
# 3. John Myles White's presentation on online SDG and his StreamStats.jl library
# Thank you all!

# Requested gist of code to produce:

#
# I just redirected the output to a dot file, then executed:
# dot -Tpdf julia.dot -o julia.pdf
function print_type_tree(t, parent=Any, seen=Set{DataType}())
# Avoid redundant edges.
t ∈ seen && return
