Description:
Cannot use "case" construction in a "for" loop in a $() sub shell.
Should work but produces parsing error.
Repeat-By:
echo $(for x in whatever; do case y in *) echo 42;; esac; done)
The closing parentheses in the case statement is being interpreted as the
closing for $(
Fix:
Probably by fixing the bash parser.
Balance the parentheses in the case statement:
echo $(for x in whatever; do case y in (*) echo 42;; esac; done)
