I assume he's doing bsr/ret to get into and
out of the sub, which is going to be significantly faster.
Who says that?
As already stated, I don't consider these as either light-weight nor
faster. Here is a benchmark.
Below are 2

Chopping out the multiplication (since that's a not-insignificant
amount of the runtime for the bsr/ret version) gives:
PIR:
real0m3.016s
user0m2.990s
sys 0m0.030s
bsr/ret
real0m0.344s
user0m0.340s

Below are 2 version of a recursive factorial program. fact(100) is
calculated 1000 times:
PIR 1.1 s
bsr/ret
