I understand that INSERT and SELECT value (without ::type) might need to be
specially casted, otherwise they end up as text.
I'd never needed to do this before and was surprised to see that I needed to
pass a types=['json'], or call json.dumps() to make it work at all.
Specifically, I thought it
For me, on both py27 and py35 (which I don't otherwise use), it's ~50% faster
to try:return dict[key]; except: pass than to test dict.get().
At least for the common case of "key in dict".
d=dict(a=1)
for i in range(1,99):
#x = d.get('a')
#if x is not None: print (d['a'])
