// Exceptions disabled: run the guarded block unconditionally, and make the

// handler body syntactically valid (it is parsed, not discarded) without a
// `catch` keyword, which `-fno-exceptions` rejects.
//
// Only `catch (...)` is provided — a typed/bound handler (`catch (const E& e)`)
// cannot be expressed this way because its body would reference an undefined
// binding. Defensive sites that only need to swallow-and-fall-through use
// `catch (...)`, which is all these toolchains require.
