too hard to evalulate changes until it's rebased on the module work |
it also tags the node with the inferred type

allow conversion from Bytes/String types to shorter length types, e.g. convert `Bytes[20]` to `Bytes[19]` this will become important when we want to allow generic bytestrings inside the type system (`Bytes[...]`) which can only be user-instantiated by converting to a known length.

test code:
```
interface Foo:
def foo(xs: Bytes[...]) -> uint256: view
def bar() -> Bytes[...]: view
def baz(xs: Bytes[...]): nonpayable
def qux() -> Bytes[...]: nonpayable
@external
def foo(f: Foo):
xs: Bytes[10] = b""
t: uint256 = staticcall f.foo(xs)
xs = convert(staticcall f.bar(), Bytes[10])
extcall f.baz(xs)
extcall f.qux()

changed the title
What I did
rework
validate_expected_typeso that it returns (and tags) the expected type instead of just validating the type. this makes it so certain calls tovalidate_expected_type()can get a concrete type, where previously the type was not known beforehand.this is a language change, generic bytes types (like from an interface) should work more as expected now.
How I did it
