Conditional compilation should allow operators

[JPeMu]

Preprocessor statements such as this:

#if not production
   ? "Debug Version"
#else
   ? "Production Version"
#end if

Give a 1091 error ("#if conditionals can only be 'true', 'false', or other #const names"). This doesn't seem to be the case for vanilla BrightScript as can be seen in the example in the Roku documentation:

Conditional Compilation - Roku Documentation

Unfortunately the Roku docs don't expand on which operators are permitted. It's probably relatively safe to assume that the logical operators (AND, OR, NOT) are OK, but what about others? The code shown above works fine on a Roku device.
