+Printing dollar from literals and variables
+
+To survive the parser, a dollar character must be doubled.
+       1 dollar literal => <single-quote-var-value>
+   1 dollar literal eol => <>
+       2 dollar literal => <$>
+       4 dollar literal => <$$>
+Some hungry part of make eats all the dollars after a :U modifier.
+       1 dollar default => <>
+       2 dollar default => <>
+       4 dollar default => <>
+This works as expected.
+      1 dollar variable => <>
+      2 dollar variable => <$>
+      4 dollar variable => <$$>
+Some hungry part of make eats all the dollars after a :U modifier.
+   1 dollar var-default => <>
+   2 dollar var-default => <$>
+   4 dollar var-default => <$$>
+
+Dollar in :S pattern
+
+              S,$,word, => <$XYword>
+             S,$X,word, => <$XY>
+            S,$$X,word, => <$XY>
+           S,$$$X,word, => <$XY>
+         S,$X,replaced, => <replaced>
+        S,$$X,replaced, => <replaced>
+       S,$$$X,replaced, => <replaced>
+
+Dollar in :C character class
+
+The A is replaced because the $$ is reduced to a single $,
+which is then resolved to the variable X with the value VAR_X.
+The effective character class becomes [VAR_XY].
+         C,[$$XY],<&>,g => <$<A><X><Y>>
+
+Dollar in :C pattern
+
+For some reason, multiple dollars are folded into one.
+           C,$,dollar,g => <>
+          C,$$,dollar,g => <>
