// Types
//
// We slap a very simple type system on top of Blockly. This is needed to ensure

// would not work).
///////////////////////////////////////////////////////////////////////////////
// There are several layers of abstraction for the type system.
// - Block are annotated with a string return type, and a string type for their
// input blocks (see blocks-custom.js). We use that as the reference semantics
// for the blocks.
// - In this "type system", we use the enum Type. Using an enum rules out more
// mistakes.
// - When emitting code, we target the "TouchDevelop types".
//
// Type inference / checking is done as follows. First, we try to assign a type
// to all variables. We do this by examining all variable assignments and
// figuring out the type from the right-hand side. There's a fixpoint computation
// (see [mkEnv]). Then, we propagate down the expected type when doing code
// generation; when generating code for a variable dereference, if the expected
// type doesn't match the inferred type, it's an error. If the type was
// undetermined as of yet, the type of the variable becomes the expected type.
