case and paste

n. [from cut and paste ] The addition of a new feature to an existing system
by selecting the code from an existing feature and pasting it in with minor
changes. Common in telephony circles because most operations in a telephone
switch are selected using case statements. Leads to software bloat. In some
circles of EMACS users this is called programming by Meta-W , because Meta-W
is the EMACS command for copying a block of text to a kill buffer in
preparation to pasting it in elsewhere. The term is condescending, implying
that the programmer is acting mindlessly rather than thinking carefully
about what is required to integrate the code for two similar cases. At DEC
(now HP), this is sometimes called clone-and-hack coding.
