exploration: Store external information in internal attributes

[anmonteiro]

Currently Melange external attributes store some internal marshaled data in the primitive payload, e.g.:

external document: t = "SOME_MARSHALED_DATA_GETS_INSERTED_HERE"

we want to explore storing that data in e.g. [@internal.melange-external "PAYLOAD_HERE"]

Hi! I opened up the above issue reasonml/reason-react#853, which I believe would be solved by this ticket. To repeat briefly, my editor is unable to handle the unexpected characters produced by the lsp when my cursor is over module definitions. I am using Emacs w/ Eglot.

Alternatively, is there a different recommended developer experience for Emacs users?

no workaround at the moment, unfortunately.

An alternative to this issue, that might be easier to prototype, is to patch the Reason outcome printer to detect that the external has marshaled information, and not print that. But it'd only work for Reason
