Yes we use exactly this kind of introspection when optimising SQL
queries in scrooge (
http://github.com/methodmissing/scrooge/tree/master ).

For our purposes we need to determine if one backtrace is different
from another - we want to make sure that we optimise each callsite
from user code individually.

Storing and comparing the output of caller is not ideal for this -
those arrays of strings can get large.  Currently we hash the top 11
items in the list and store the hash as a signature.  But even so
dozens (or however deep the stack is) of strings must be created each
time by caller anyway - it's not terribly fast.

What would be most advantageous to us would be if Backtrace#hash were
added, and generated a hash faster without having to create so many
strings as is the current case.
