[tpm] Subroutine arcana

[arocker at vex.net]

Does anyone know if it is legitimate to use an anonymous subroutine in a
named one? I've run across a case in someone else's code, and the 
expression using the anonymous routine simply seems to be ignored, neither
executing nor generating a complaint.

I believe, (and taught), that named subroutines cannot be nested, but when
I sought guidance in the canon, it was strangely silent about the nesting
of either type.
