public class ExtractMsgVariablesVisitor extends AbstractSoyNodeVisitor<Void>
MsgFallbackGroupNodes to separate {let} and print nodes.
We then move the let node to the nearest block ancestor, so that the print node can be emitted as
an expression instead of a statement. After this pass, all MsgFallbackGroupNodes will only appear
inside LetContentNodes.
TODO(slaks): Generalize to extract all nodes that create statements but must appear in expression
context (MsgHtmlTagNode, CallParamNode, LogNode, & idom attribute values)
to variables. This will let us completely remove the many paths in jssrc that conditionally emit
temporary variables.
exec(com.google.template.soy.soytree.SoyNode) must be called on a full parse tree.
