GuestLanguageParser

@DelicateElideApi
interface GuestLanguageParser

A GuestLanguage feature for parsing Source code in a given PolyglotContext, returning an executable PolyglotValue.

Install an implementation of this interface using a PolyglotContextElement with a key obtained from GuestLanguageParser.contextElementFor, with the target language as identifier, to intercept calls to PolyglotContext.parse.

PolyglotContext implementations will always prefer delegating parsing logic to a GuestLanguageParser for the relevant source if one is registered, falling back to their defaults if none is found.
