Functions guide: replace flawed zoo analogy for scope - #45421
Merged
Conversation
…alogy The zoo analogy implied the global scope reaches into function scopes, which is backwards. Use an apartment-building analogy instead, where private apartments represent function scope and shared common areas represent the global scope.

LGTM; thanks, @BaconMan1168. I've made some structural suggestions. I think having the two parts of the analogy as bullets makes sense.

Description
Replaces the zoo/zookeeper analogy in the "Function scope and conflicts" section with an apartment-building analogy: private apartments represent function scope, and shared common areas (pool, gym, rec room) represent the global scope. Also removes the now-unused zoo illustration.
Motivation
The zoo analogy was backwards/misleading — it framed the "zoo keeper" (global scope) as reaching into every enclosure (function scope), when the actual point is the reverse: things declared in global scope are accessible to narrower scopes, not the other way around.
Additional details
The apartment-building analogy was proposed by @wbamberg in the issue thread and confirmed as clearer by the reporter @mao-sz. No other content on the page was changed.
