Open Radar

 
Summary:
Using Xcode or the REPL from the command line, enter that simple line of code. I don't get a response

Steps to Reproduce:
1. open REPL or playground

2. Enter:

let d = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

3. CPU usage spikes, no response produced.

4. let b = 1 + 2 + 3 + 4 + 5 provides reasonably quick response.

numbers above 5 seem to invoke the slowdown

Expected Results:
quick evaluation of simple line of code

Actual Results:
bogging down CPU, errors like:
