> It would be nice to allow developers to extend hive query language, making possible to
use custom wildcards on queries. 
> People uses Python or R to iterate over vectors or lists and create SQL commands, this
could be implemented directly on sql syntax.
> For example this python script:
> >>> sql = "SELECT state, "
> >>> for i in range(10):
> ...   sql += "   sum(case when type = " + str(i) + " then value end) as sum_of_" + str(i)
+ " ,"
> ...
> >>> sql += " count(1) as  total FROM table"
> >>> print(sql)
> Could be written directly in extended sql like this:
> SELECT state,
> %for id = 1 to 10%
>    sum(case when type = %id% then value end) as sum_of_%id%,
> %end%
> , count(1) as total
> FROM table
> GROUP BY state
> This kind of extensibility can be easily added if we add a new hook after VariableSubstitution
call on Driver.compile method.
