Collect a stream into a value.
Signature

Parameters
closure
: The closure to run once the stream is collected.
Input/output types:

---|---|
any | any |
Examples
Use the second value in the stream

Notes
If provided, run a closure with the collected value as input.
The entire stream will be collected into one value in memory, so if the stream is particularly large, this can cause high memory usage.
