immediate floats produced by the constrain on the '=' operator.

1. Prefer "native-compiled" to "native compiled".
The adjective "native-compiled" with the hyphen is generally more
consistent with the typical pattern in English, especially when the
compound modifies a noun (e.g., "native-compiled code").

2. Prefer "natively compiled" to "natively-compiled".
The adverb "natively" modifies "compiled", and it is standard not
to hyphenate an adverb + adjective combination when the adverb ends
in -ly (e.g., "code that is natively compiled").

For example, note that we say "high-speed internet" but "highly
performant code".
