[Boost-users] [preprocessor] removing parentheses

I have a single macro parameter which allows its passed value to contain 
commas. Therefore the user of the macro needs parentheses around the 
parameter if it contains one or more commas ( to does not have to ). 
When processing this parameter in a macro I would like to remove the 
outer parentheses if they are there before passing the value on for 
further processing. Is there a way to do this using some preprocessor 
library macro ?
