I have a couple of sections of code that I don’t want any warnings  
displayed  
for. I’d still like the warnings for the rest of the application.

Can I turn warnings on and off programatically?

Yes, the idiom is $VERBOSE = nil.

– fxn

% irb  
irb(main):001:0\> a = []  
=\> []  
irb(main):002:0\> a.push (0)  
(irb):2: warning: don’t put space before argument parentheses  
=\> [0]  
irb(main):003:0\> current\_W = $VERBOSE  
=\> false  
irb(main):004:0\> $VERBOSE = nil  
=\> nil  
irb(main):005:0\> a.push (0)  
=\> [0, 0]  
irb(main):006:0\> $VERBOSE = current\_W  
=\> false  
irb(main):007:0\> a.push (0)  
(irb):7: warning: don’t put space before argument parentheses  
=\> [0, 0, 0]
