Function rustc_mir_transform::simplify_try::try_eat

fn try_eat<'a, 'tcx>(
    stmt_iter: &mut Peekable<Enumerate<Iter<'a, Statement<'tcx>>>>,
    test: impl Fn(&'a Statement<'tcx>) -> bool,
    action: impl FnMut(usize, &'a Statement<'tcx>)
)

Eats consecutive Statements which match test, performing the specified action for each. The iterator stmt_iter is not advanced if none were matched.
