[PATCH 2/2] libstdc++: Use template form for pretty-printing tuple elements

Paul Smith psmith@gnu.org

std::tuple elements are retrieved via std::get<> (template) not
[] (array); have the generated output string match this.

libstdc++-v3/ChangeLog:

        * python/libstdcxx/v6/printers.py (StdTuplePrinter): Use <> not [].
---
The previous patch seems uncontroversial to me.  I don't know about this one:
I'm not sure if there's any precedent for this type of output although to me
it looks better since tuples cannot be retrieved via array indexing.
