Close your eyes and tap your heels thrice.
No, really, ignoring things is as easy as not looking at them. (In all=20
likelihood you should fix your code to not have warnings instead.)

I agree with Konrad that you should probably fix warnings rather than
ignore, but -W is the command line flag you want. -W1 is standard, -
W2 is verbose, -W0 is no warnings whatsoever.

Is there a possibility to ignore warnings dynamically? - I mean,
sometimes it's helpful to redefine constants, which will always produce
a warning. I want to suppress warnings for these lines only.

Or set one of the variables $-v, $-w, $VERBOSE to 'nil'.

Option $-v
-W0 nil
-W1 false
-W2 true

Well - it looks fine, because it's no dirty trick.

Or cover your head with your towel, rubyists should ALWAYS have their
towel handy.

And as the Hitchhiker's Guide to Ruby explains this is also the best

Yuck.

I've pushed for structured warnings in the past, but it has fallen on
deaf ears.

Ruby will spit out warnings for white space - with no coding errors,

and many programming languages output warnings for using anything but
the most basic techniques

so weather you're a novice or a seasoned veteran there are valid reasons
to suppress warnings: after all, it does have W levels
