``` const { parse } = require('esprima'); const staticEval = require('static-eval'); const ast = parse('(() => 1)()'); const val = staticEval(ast.body[0].expression, {}, { allowAccessToMethodsOnFunctions: true }); // val is undefined ``` The expression I was actually trying to evaluate looks more like `'[1,2,3].map(x => x)'` Is there some workaround?
