What is the best way to filter out all elements in a data structure that don't obey a certain predicate? i.e. a method similar to the "filter" methods in functional programming languages.

Filtration, the technique used to separate solids from liquids, is the act of pouring a mixture onto a membrane (filter paper) that allows the passage of liquid (the filtrate) and results in the collection of the solid.
A "filter" program is simply a program which reads from the standard input stream ( stdin ) and writes to the standard output stream ( stdout ).
The FILTER function allows you to filter a range of data based on criteria you define.
The four primary types of filters include the low-pass filter, the high-pass filter, the band-pass filter, and the notch filter (or the band-reject or band-stop filter).
STL has remove_if and remove_copy_if algorithms.
