Steps to reproduce the problem:
1. eval('var a = 123;'); console.log('a');
2. paste above code outside class context, runs fine
3. paste code inside class context (static), throws error

What is the expected behavior?
eval
Should allow new variables to be set in class context.

What went wrong?
"[Variable] is not defined." error thrown.

Did this work before? No
