Question: is it possible to avoid "EvalError unsafe-eval"?

[beck]

Sinon version: 1.13.0 (master)
Environment: OSX / Atom Package Manager (apm 0.142.0) / node 0.10.35

Context - working an Atom.io package, specifically a code linter and the tests make liberal use of Sinon.

When using a stub it throws:

EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self'".

Found one attempt at a solution called loophole but it has issues.

Looking for any advice / suggestions?

I am also developing specs for my package in Atom that are trying to stub the fs. I too get the original unsafe-eval message and when using the loophole package I get reset undefined! I'd like to be able to stub this!

stubWriteFileSync = sinon.stub(fs, 'writeFileSync').return(undefined)
gets

whereas
allowUnsafeEval -> stubWriteFileSync = sinon.stub(fs, 'writeFileSync').return(undefined)
gets
