Filtering functions. |
filterfun returns a function that takes a single argument. It
binds the filter functions given to it in the environment of the
returned function. These functions are applied sequentially (in the
order they were given to filterfun). The function returns
FALSE (and exits) when the first filter function returns
FALSE otherwise it returns TRUE.
