Timing
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.
`Timing(expr)` evaluates `expr` and return a `Pair` of the number of second elapsed for the evaluation, and the value of the evaluation
Timing(value, repeat: integer?) -> tuple<result: value, time: number>as compute-engine declares it
