Deprecated. Invoking this procedure generates a warning.

Here's how to compute 'n choose k' like a real nerd. DEPRECATED: As of tcl8.5, Tcl has native support for 'lambda' provided by means of 'apply' per TIP 194. Tcllib provides a 'lambda' package with procs that make use of it.

Parameters:

n
k
