This is a strawman PR to implement coercion of `t` to `opt t` when decoding values.

The formatter insists on this change.
This is something that I've also encountered lately, if possible it would be great to merge it- |
public decodeValue(b: Pipe, t: Type): [T] | [] { | ||
const opt = this.checkType(t); | ||
if (!(opt instanceof OptClass)) { | ||
throw new Error('Not an option type'); | ||
return [this._type.decodeValue(b, opt)]; |

I did some tests, and this should be a little bit different
const type = Rec()
type._type = opt
return [this._type.decodeValue(b, type)];
Otherwise this will throw another error

Thanks. Could you provide a full test-case of an input the crashes with the current code but succeeds using your suggested change?
It would be helpful to add it to the actual test suite.
Description
This is a strawman PR to implement coercion of
t
toopt t
when decoding values.The test suite still passes, but I'm not sure if I broke something else in the process.
Also it uses control flow by exception, which is rather ugly.
