Now it's not *that* easy, there might also be square brackets in string
and character constants, in comments, etc.

There are tons of things in Chez Scheme that cannot be defined by using
only the functionality specified by the R*RS.  For instance, there is
the #& reader syntax, an error handling and reporting mechanism (error
handling still isn't defined in the R*RS last time I looked), functions
for exception handling, dynamic-wind and fluid-let (how are you going
to define this in an R*RS-implementation?), etc.
