Better error messages when a sequence is indexed with a non-integer.

Browse Source 
Previously, this said "unsubscriptable object"; in 1.5.1, the reverse
problem existed, where None[''] would complain about a non-integer
index.  This fix does the right thing in all cases (for get, set and
del item).
