+# 尔 simplification pass. The idea is to drop most occurences of 尔
+# corresponding to <r> (not to <l> or <ll>) from a word if there is another /l/
+# sound nearby. There is a vague pattern like this in the data, but the details
+# remain to be determined. At the moment, this does nothing, it just puts 尔 in
+# for every <r> in a syllable coda.
