@cindex modifying operators
The modifying C/C++ operators @code{+=}, @code{-=}, @code{*=}, @code{/=},
@code{&=}, @code{|=}, @code{^=}, @code{<<=}, @code{>>=}
are not available by default because their
use tends to make programs unreadable. It is trivial to get away without
them. However, if you feel that you absolutely need these operators
to get happy, then add
@example
#define WANT_OBFUSCATING_OPERATORS
@end example
@cindex @code{WANT_OBFUSCATING_OPERATORS}
to the beginning of your source files, before the inclusion of any CLN
include files. This flag will enable the following operators:

Note that by using these modifying operators, you don't gain efficiency:
In CLN @samp{x += y;} is exactly the same as @samp{x = x+y;}, not more
efficient.
