Method expr

src/compute-engine/index.ts:1571–1582

Return a boxed expression from a number, string or expression input. * Calls `ce.function()`, `ce.number()` or `ce.symbol()` as appropriate.

    expr: NumericValue | ExpressionInput,
    options?: {
      form?: FormOption;

      structural?: boolean;

  /** Instrumentation counters for the auto-compilation of lazy-`Map` element
   * lambdas on numeric drains — compile attempts, elements served by a
   * compiled function, dependency re-validations, recompiles, per-element
   * interpreter fallbacks and NaN double-checks. This is the only surface that
   * says whether a given `Map` drain compiled, re-validated or fell back, and
   * it is exposed here because that question is asked from a consumer install,
   * where a module-level export of `library/map-auto-compile.ts` is not
   * reachable (no subpath export, and the symbol does not survive
   * minification).
   *
   * The counters are process-global and cumulative, not per-engine — the
   * compile cache they instrument is a module-level `WeakMap` shared by every
   * engine in the process — so every engine returns the same object, and a
   * caller measures a single drain by reading the counters before and after it
   * and taking the difference.
