Clarification about what this "unsupported" syntax is referring to?

[getify]

This is listed under the "unsupported" section:

a?.b`{c}`

What is that intended to mean, specifically, the {c} part? Was that intended to be:

a?.b`${c}`

Moreover, is it saying that:

mylib?.mytag`my string`

will be invalid syntax?

[ljharb]

Yes, see #54.

[jridgewell]

Correct. We do not currently support optional tagged templates, but explicitly forbidding it now allows us to avoid an ASI hazard if we do add support for it in the future.

[getify]

The point of this issue was, the README should change

a?.b`{c}`

to

a?.b`${c}`

or

a?.b`c`

because {c} is unnecessarily confusing as a cited example.

Done
