About
Generated from the engine's own definition: compute-engine's symbol, which we neither extend nor document by hand. No examples yet — the crosswalk is the reason it has a page.
Return information about an expression as a dictionary: its kind (symbol, constant, function, number, string, expression), its static type and, when applicable, its name, value, signature, clause listing, algebraic attributes, description, wikidata and url.
