This limits productivity in the early stage of code developement, when the types may change quite a bit. At he moment every change to a custom type requires either repl restart or type rename.
I run into this problem in sublime-iJulia initially were whole buffer (which has a type definition) can be evaluated only once. The next time type section needs to be commented out. But this is more a plugin specific issue. Thanks for a quick feedback, Kuba
