... and the same with RBF(gamma(3/2,1)), except that

(a) The error message is now "TypeError: gamma() takes no arguments (1 
given)"
(b) The situation is now more serious, since RIF(gamma(3/2,1)) doesn't work 
either.

Of course the incomplete gamma function was implemented in ARB a long time 
ago, so there is really no good reason for this to happen.
