I use SDL daily... But my SDL is DEC?s Structure Definition Language, a
language to define structures and export them to be used in Macro-32,
Bliss, and C.

Well, there you go--another reason for the tower of Babel.  STL, at
first glance for me, brings up "Standard Template Library".  I have no
doubt that there are at least a half-dozen other language-related
meanings for this acronym.
SDL = System Definition Language, from the 1960s, almost completely
forgotten now.  Then there's SDL = Specification and Description Language:

If I had to shake a stick at all computer languages, I'd run out of
sticks.
