case and paste
[from `cut and paste'] n. 1. The addition of a new
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.
