...and yet bash-2.01 will have a fix. I fixed the bash parsing code
so that it requires an arithmetic command to begin with `((', end
with `))', and have an equal number of open and close parens. If it
does not end with `))', it is treated as a nested subshell. A non-
balancing number of open and close parens is treated as a syntax error.
