Imports
org.jruby.ir.IRScope, .IRVisitor, org.jruby.ir.transformations.inlining.CloneInfo, org.jruby.parser.StaticScope, org.jruby.runtime.DynamicScope, .ThreadContext, org.jruby.runtime.builtin.IRubyObject, java.util.List
Reference a StaticScope/IRScope. This could be used wherever we know a staticscope will be used but we initially favor CurrentScope as it is a single instance and it reduces an object allocation for every scope in the system.

Note

we store IRScope because JIT can easily store IRScopes vs making new JIT infrastructure for StaticScope (and from a scoping standpoint these two types are 1:1). However, once we inline we are migrating things referencing a currentscope which no longer exists. In this case, we need replace CurrentScope with a Scope.

public void
addUsedVariables(List<Variable> l)

Implements abstract org.jruby.ir.operands.Operand.addUsedVariables.

Append the list of variables used in this operand to the input list -- force every operand to implement this because a missing implementation can cause bad failures.
