Previously when parsing an initializer list, the type passed to `parse_initializer` was not updated to reflect the child type, this caused implicit conversions to not work and nested initializer lists to not be allowed.

@jimblandy thanks for the suggestion, I've also took some time to improve the documentation, could you give it another look. |

There was a problem hiding this comment.
You're counting on validation to complain if there are too many components - correct? (It does, in naga::valid::compose::validate_compose.)
This PR is still an improvement over the status quo, but tolerating bad indices here does mean that if someone supplies too many values in the initializer, you're going to be passing meaningless types to implicit_conversion, and the error messages will be pretty confusing. That is, you'll get weird GLSL front end errors, instead of the nice "too many components" error from the validator, because you'll never make it that far.
