Regression with "Part options support for $n"

[pinguet62]

Reporting a bug?

#2170
#2174
The 2 PR change typing of n() from simple string to string | Intl.NumberFormatPart[].
Now it's necessary to complexify all usages of n(): we have to check type and cast or convert data...

Probably same issue with d date formatter!

Expected behavior

The typing should be dynamic, depending the { part: true } option value:

n(42) // string
n(42, {}) // string
n(42, { part: false }) // string
n(42, { part: true }) // Intl.NumberFormatPart[]

Reproduction

<AComponent :aPropsOfTypeString="n(42)" />

const { n } = useI18n()
const value: string = n(42)

System Info

Can confirm that this is also a problem for d(). A workaround for this is to add explicit types d<Date, string, string>(), but this should be included like proposed in the expected behavior.
