a independent implementation of parametrized queries can looks like attached patch:
this code is simple without any unexpected behave.
parameters are used when user doesn't require escaping and when PARAMETRIZED_QUERIES variable is on
Regards
here is a Daniel's syntax patch
The independent implementation of using query parameters is good idea, the patch looks well, and there is a agreement with Tom.
I implemented a Daniel proposal - it is few lines, but personally I prefer curly bracket syntax against `` syntax. When separator is double char, then the correct implementation will not be simple - the bad combinations "` ``, `` `" should be handled better. I wrote my arguments for my design, but if these arguments are not important for any other, then I can accept any other designs.
