No implicit any errors

[timruffles]

I'm having the following errors:

 ERROR in node_modules/@ngrx/core/src/compose.ts (12,43): Rest parameter 'functions' implicitly has an 'any[]' type.
  node_modules/@ngrx/core/src/compose.ts (13,19): Parameter 'arg' implicitly has an 'any' type.

when using this repo with: Typescript 2.2.2 and the below tsconfig. From looking at the code there is a type annotation, but TS seems to be failing at inferring the types from it.

I've not dug into best-practices for publishing TS modules, but is the lack of explicit declaration file in package.json, or a index.d.ts forcing TypeScript to dig through the package and re-validate it? I note the TypeScript docs suggests either types in package.json or a index.d.ts (the approach Angular itself takes).
