The means to construct your own filters.

The default filters available to a template are documented by the subsequent categories.

These filters cannot be overriden and attempting to supply your own filters to renderWith will cause the similarly named filters to disappear when they are merged with the prelude during evaluation. (See: union)

• ! :: Bool -> Bool (See: not)
• && :: Bool -> Bool -> Bool
• || :: Bool -> Bool -> Bool

• == :: a -> a -> Bool
• != :: a -> a -> Bool (See: /=)

• > :: a -> a -> Bool
• >= :: a -> a -> Bool
• <= :: a -> a -> Bool
• <= :: a -> a -> Bool

• + :: Scientific -> Scientific -> Scientific
• - :: Scientific -> Scientific -> Scientific
• * :: Scientific -> Scientific -> Scientific
