| ### Control flow and short-circuiting | ||
|
|
||
| Control-flow operators are implemented carefully to preserve simfil’s “truthy but value‑preserving” semantics. `AnyExpr` and `EachExpr` aggregate over a list of argument expressions; they rely on the `boolify` helper, which converts a `Value` to a boolean with the usual rules but treats `undef` as false. `AnyExpr` stops evaluation as soon as one argument evaluates to true and reports either `undef` (if no conclusive value was seen) or a boolean summarising the result. `EachExpr` behaves symmetrically: it halts on the first false argument and only returns true if all arguments evaluate to true and none to `undef`. |
