583ca906b3 Significantly reduce dependencies. 
In conjunction with a small change to syntax/parse, this means
that `typed/racket/base` no longer depends on `racket/set`,
`racket/contract/base`, or `racket/generic`.

Timings on my machine go from ~200ms for `#lang typed/racket/base`
as the whole file, to ~100ms. For comparison, `racket/base` is 30ms
and `#lang racket` is 150ms. `#lang typed/racket` is ~200ms with
this change.

Changes include:
 - not using `in-syntax`
 - switching to `syntax/parse/pre`
 - avoiding `template` from `syntax/parse`

c70910aaa0 Fix type restriction in values->tc-results 
Previously the restriction didn't account for traversing
the object type with the given path. This also relies on
the previous commit that adds subtyping on filters.

(because this change seems to introduce filters which
 only differ by an unrolling of a recursive type, but
 the old subtyping only worked for identical types)
 2015-04-02 10:58:45 -04:00
Asumu Takikawa
8acc86bb9b Add subtyping for types inside filters 
This makes a type like

  (-> Any Boolean : #:+ Integer)

a subtype of a type like

  (-> Any Boolean : #:+ Number)

For not filters, the direction is reversed.

4709536653 Split prims.rkt to reduce dependencies. 
There are several new files: one for structure prims, one for
annotation-related prims, one for contract related ones. The prims-contract
file uses trickery with submodules to avoid a direct dependency
on `racket/contract`.

Additionally, the rewritten versions of `for/set` et al now use
a submodule to avoid a direct dependency on `racket/set`.

33543ce054 Use absent in some row poly class contracts 
When exporting row polymorphic functions from TR, just
use absent clauses to ensure that TR won't accidentally
try to add pre-existing fields/methods. No sealing is
needed because the typechecker enforces parameteric use
of the class.

1469306a8e use free-id=? instead of bound-id=? for letrec analysis

fed9ac40eb Adjust the recursive type alias registration pass

ae0717d970 Move generated contracted provides to a submodule. 
This allows the main TR module not to explicitly
depend on the contract library. Each exported name
can be redirected to either the original name (for a
typed client) or to another macro (for an untyped
client) which expands to a `local-require` for the
relevant submodule (named `#%contract-defs`).

Thanks to Matthew for the initial idea and an
implementation in plai-typed that this is based on.
