Example 7

Example 7: Eval is evil (almost always)

Analyze the impact of closures on memory

See that eval retains a reference on all the variables of the closure.

1. Start the creation of new closures
2. Take a heap snapshot
3. Find the closures (named lC, sC, and eC)

Closures maintain hold on large string

Closures maintain hold only on small strings

Closures with eval

Stop and clear
