I've seen some documentation for all those languages except B, but I 
never programmed in any of: SNOBOL, B, nor APL.  I was sent on a 3 day 
PL/1 course, but never used it 'in anger'.

I once tried to discuss general programming ideas with a colleague, and 
started talking about a section of code.  They then proceeded to tell me 
the definition of SECTION in COBOL in detail, I didn't bother to tell 
them that I knew 3 things about SECTIONs in COBOL that they hadn't 
mentioned.  I gave up the discussion, saw no point in continuing, and I 
didn't want to appear patronising.

Until one has programmed in several languages, preferably of different 
types, it is difficult to separate out programming concepts from the 
philosophy and implementation of individual languages.

I think any Master Programmer should have fluency in at least 3 
languages and familiarity with at least 3 more.  So I think at least 3 
languages should be taught to CS students.  And of course the importance 
of how to RTFM effectively!

Once I helped a colleague debug a Smalltalk example based on a magazine 
article I'd read 2 years earlier.  I'm certain they implicitly assumed 
that I was for more experienced in Smalltalk than I was!  Perhaps I 
should ask her, but she's probably forgotten -- that was about 30 years 
ago.  Now I've been married to her for 25 years,

Another time I helped someone develop a screen saver in Visual Basic.  
Though it was many years later before I realized the name of the 
language.  I'd never seen VB before.  I even explained the OnEvent 
concept even though it was totally new to me, but I still successfully 
helped them to implement at least one such construct in the screen 
saver.  Having experience with a wide variety of different programming 
languages was a huge advantage.
