Angle Bracket Placement
Bad placement of angle brackets (<>) causes many template syntax errors. Make sure that you use proper spacing and parentheses to distinguish angle brackets from operators such as >> and ->. For example:
TempClass< float, a > b ? a : b > test1;
should be rewritten as
TempClass< float, (a > b ? a : b) > test1;
Similarly, pay extra attention when using macros that use angle brackets as template arguments.
