The infix macro uses ‘**’ as exponentiation operator and ‘^’ as bitwise XOR
operator; this is controversial because a lot of people, especially LaTeX users, are used to think
of ‘^’ as exponentiation operator. The C language has established a tradition to interpret
‘^’ as bitwise exclusive OR operator, and the Python language has adopted it; MMCK Infix
sticks to it, too.
The C language has established a tradition of interpreting the single vertical bar ‘|’ as bitwise inclusive OR operator and the double vertical bar as ‘||’ as logical inclusive OR operator.
In the Scheme language the vertical bar is used in the block comments delimiters ‘#| … |#’. Some text editors for software programmers handle the vertical bar specially in Scheme mode, in particular for syntax highlighting.
It would be possible to extend the Scheme reader to allow ‘|’ and ‘||’ to be symbols, but,
at present, this confuses some text editors in a way that is not easy to fix. So, for now, rather
than the vertical bar, infix recognises the Unicode character vertical bar extension
(‘\x23D0;’) as bitwise inclusive OR and the double vertical bar extension as logical inclusive
OR.
