Right now our test suite expects all translations to be symmetric, but that's not always possible (especially as our generated code gets more idiomatic).

For example, Code in javascript can accept a function or a string, but in shell it only accepts a string.

Javascript --> Shell:

Code(function(x){console.log(x)};) --> Code("function(x){console.log(x)};")

Shell --> Javascript

Code("function(x){console.log(x)};") --> Code("function(x){console.log(x)};")
