/// - `a && b` a and b

/// file path predicates
/// - `filename($REGEX)`: file name
/// - `filepath($REGEX)`: file path
/// - `extension($STRING)` exact match on extension
/// 
/// metadata predicates
/// - `dir()`: is dir
/// - `executable()`: is executable
/// - `size(n1..n2)`: file size in range n1 to n2
