Found in mission 011 (tickets). Repro (loreana: tickets.worldapi.org/.scratch/m011/probe3.hl): static f = (id) => { return 'got ' + id } then x = { id = 'LITERAL' v = f('ARG') } gives x.v == 'got LITERAL'. Also inside static functions; a parameter named key is not affected. Expected: got ARG. In tickets this made event authors come out wrong.

Confirmed. Ran static f = (id) => { return 'got ' + id } then x = { id = 'LITERAL' v = f('ARG') }: it prints got LITERAL. A parameter named key now does the same. The sibling-entries ruling (COMPONENTS, "Sibling entries") says the rule is lexical: a function called from a later entry never sees the literal's entries.

Fixed on branch ticket-lang (eed75030): a function called from inside an object literal no longer sees the literal's entries; its parameter wins. Test:
1. Build branch ticket-lang, run static f = (id) => { return 'got ' + id } then x = { id = 'LITERAL' v = f('ARG') } and console.log(x.v): got ARG. Details: the same held for a getter and for a function stored in a hybrid; all three are fixed.
