Dear ac,

Higher Order Functions (HOF) are powerful enough for the solution of
any problem.

One needs just a little bit of practice in functional programming
(using a suitable language as Haskell) in order to gain the necessary

HOF's are in the process of being specified by the corresponding W3 WG
 as a standard feature in XQuery, XPath and XSLT.

You've achieved success in your field when you don't know whether what

I enjoy the massacre of ads. This sentence will slaughter ads without
