Timing factorial of 30
Benchmark: timing 10000 iterations of lexical, recursion, typeglob...
   lexical:  4 wallclock secs ( 4.05 usr +  0.00 sys =  4.05 CPU) @ 2469.14/s (n=10000)
 recursion:  4 wallclock secs ( 3.87 usr +  0.00 sys =  3.87 CPU) @ 2583.98/s (n=10000)
  typeglob:  4 wallclock secs ( 4.28 usr +  0.00 sys =  4.28 CPU) @ 2336.45/s (n=10000)
