Description

The following test passes with the legacy parser but fails with Parrot

// legacy parser
def s1 = $/this $$/ is an escaped dollar forward slash/$
assert s1 == 'this $/ is an escaped dollar forward slash'

// antlr4 enabled (parrot)
assert s1 == 'this $/ is an escaped dollar forward slash'
       |  |
       |  false
       this / is an escaped dollar forward slash

Noticed this when I inadvertently changed a spec test in commit 0fb89906aa. When testing for an escaped dollar slash the test had to be changed (commit 942cf4eb3e) to pass using the Antlr4 parser.

Based on the dollar slashy docs I am not sure if the old behavior is correct or not.
