I would prefer using indentation and to align hte '(' and the ')'
vertically.

Also I would even more prefer "begin" and "end" over '(' and ')'.
Thats a readability-issue.

But it seems, your problem could be solved without a second
match-statement.
But, just in case, one day you will need a nested one,
you may remember my comment here.

Of course it's a matter of taste, what I mendtioned here.
