Why are non-strict arrays more difficult to reason about in terms of performance?

because it’s hard to predict what an array operation will do

you get the same result, but maybe do more work / more memory accesses to get it

When might one reach for vectors/gvectors over arrays?

I like vectors for 1–2 dimensional data

@greg It looks like (1) Travis-CI has upgraded to Sierra, and (2) Apple fixed a bug in setenv (that Racket was working around) as of Sierra.
