I find myself copy-pasting the same list of built-in scalar names in every new project we start.
In many cases, built-in types/directives should be handled differently so having such simple predicates save a lot of code lines.
Because of circular dependencies, I couldn't figure out file suitable for
builtInTypes
andisBuiltInType
. That's why I created a new one:src/type/builtins.js
.Is it an appropriate filename or should I put somewhere else?
