To be more precise: If I understand correctly, the preparser can be made to accept any syntax, provided that this syntax is in no conflict with valid Python syntax. There is a special meaning of "?" and "??" in Python, but I think there isn't a special meaning to "!". Sage accepts "!" at the beginning of a line, meaning that it executes a shell command, such as sage: !ls But it should be possible that the preparser could turn "(expression)!" into "gamma(expression+1)". Do people agree? Unfortunately I do not volonteer to implement it, I' not familiar with the innards of the preparser.
