You might be thinking about ||=
||= assigns a value to a variable if the variable is nil

e.g. 

x = 5
x ||= 88
x  #=> 5

y = nil
y ||= 88
y  # => 88


I believe a |= b "ORs" the bits in a and b and assigns them to a

Hi people,

Did I dream about an opeartor |=?

I can't find any reference to it in the online docs, yet I think I've
seen 
it in some samples.

What does it do?

TIA
