		@language-haskell-extract@ contains some useful helper functions on top of Template Haskell.
		
		@functionExtractor@ extracts all functions after a regexp-pattern.
		
		&gt; foo = "test"
		&gt; boo = "testing"
		&gt; bar = $(functionExtractor "oo$")
		
		will automagically extract the functions ending with @oo@ such as
		
		&gt; bar = [("foo",foo), ("boo",boo)]
		
		This can be useful if you wish to extract all functions beginning with test (for a test-framework)
		or all functions beginning with wc (for a web service).
		
		@functionExtractorMap@ works like @functionsExtractor@ but applies a function over all function-pairs.
		
		This functions is useful if the common return type of the functions is a type class.
		
		Example:
		
		&gt; secondTypeclassTest =
		&gt;   do let expected = ["45", "88.8", "\"hej\""]
		&gt;          actual = $(functionExtractorMap "^tc" [|\n f -&gt; show f|] )
		&gt;      expected @=? actual
		&gt;
		&gt; tcInt :: Integer
		&gt; tcInt = 45
		&gt;
		&gt; tcDouble :: Double
		&gt; tcDouble = 88.8
		&gt;
		&gt; tcString :: String
		&gt; tcString = "hej"
