I am somewhat confused.

When reading the blog post on:

http://www.juliabloggers.com/using-julias-type-system-for-hidden-performance-gains/


the first benchmark says that: "*Notice that the vector of matrices is 300x 
slower on an i7 computer.*"
Note that the Matrices in this vector (`test2()`) are holding elements of 
type float, while for the other (`test1()`, `test3()`) it is ints.

Switching Float to Int in `test2()` makes the vector of arrays faster than 
`test1()` and `test2()`. Which is consistent with the findings of the same 
author in his original blog post.

sooo...? :)

this is on julia 0.4.5 for my own benchmarks, which agree with the results 
from the second link.
