Uwe Schindler commented on SOLR-5707:
-------------------------------------

This standard specifies one departure from the grammar given in the Unicode
standard: The dollar sign ($) and the underscore (_) are permitted anywhere in
an identifier. The dollar sign is intended for use only in mechanically
generated code.

So this is in my opinion a bug, that the ANTLR parser does not accept $ in
variables. Maybe [~rcmuir] knows the background about this limitation.
