public Object retrieve(ThreadContext context, IRubyObject self, StaticScope currScope, DynamicScope currDynScope, Object[] temp)

Overrides org.jruby.ir.operands.ImmutableLiteral.retrieve.

Doc from org.jruby.ir.operands.ImmutableLiteral.retrieve.

retrieve the live value represented by this immutable literal. An interesting property of knowing something cannot change at compile time is that all information necessary to construct it is also known at compile time. We don't pre-create these since we don't want to assume the cost of constructing literals which may never be used.
