[DB-SIG] Towards a single parameter style

[Daniel Dittmar]

- those wanting to write portable programs find the multiple parameter 
styles annoying
- those using only one driver have probably become fond of their current 
style

To make it possible to support multiple styles in one driver, I propose 
the following:
- connection.cursor () gets an optional keyword parameter 'paramstyle'
- connection has a writeable attribute which gives the default for this 
parameter (or perhaps a mapping named 'cursorOptions', in case we want 
to support more options)

Those wanting to switch to the 'standard' parameter style (whatever that 
may be) will have to change only the part containing the connect, which 
is driver specific anyway.

This might work for the current execute() discussion (keyword args vs. 
dictionary) as well.

This does not mean that I propose that drivers should be required to 
support more than one style.
