Glimmer is compiled incorrectly

[NullVoxPopuli]

in particular, type-imports are making it in to the dist-output as values, which then errors when checking under typescript (but not runtime) due to the import not existing.

For example, @glimmer/manager imports Reference from @glimmer/reference, but that import should not be present at all in the dist output, because in the source it is a type import.

or maybe something else is going on, it's so hard to tell

oh actually, this is true, the compiled output of @glimmer/reference doesn't include Reference

[NullVoxPopuli]

looks like this is due to export { value, type AType } from .../

AType never makes it to the output

or no, it's just hidden in that super long line at the bottom.
what is goin on in my consuming project then....
