Please put effort into a good IDE that leverages the type system! I&#x27;ve been using Julia for two years now, and there&#x27;s enough code to navigate through that it&#x27;s becoming difficult to maintain. I&#x27;m really starting to miss Java&#x2F;C#&#x2F; even C++ IDEs where you can easily jump to a definition or get a non-fuzzy autocomplete. Not to mention the refactoring support of the IntelliJ products. For a language that promises to handle both the high level and the low level, it really is not scaling well with codebase size. I&#x27;ve also been reassessing my needs and realizing that only about 20% of my codebase is quantitative code, and then with most of the work being sent off to raw CUDA or Theano. So I&#x27;m actively considering a better tooled language. I love how expressive Julia is, but that may be getting in the way of tooling. One issue that would help a lot is return type declarations (<a href="https:&#x2F;&#x2F;github.com&#x2F;JuliaLang&#x2F;julia&#x2F;issues&#x2F;1090" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;JuliaLang&#x2F;julia&#x2F;issues&#x2F;1090</a>). Return types would dramatically ease creation of IDE plugins.
