[Scutigena-code] improved random.tcl

[miguel s. <mi...@ut...>]

If we are allowed to inline code (gcc is doing it explicitly, don't know 
about the rest), we run 3 times faster! Attached an inlining version of 
random.tcl

It is fair to say that this is not standard tcl coding practice ... 
except when coding for speed. tcllib has some examples.
