Is MySQL planning to implement CTE and Window functions ?

[Steven NAUDET]

Hi guys,

I can't find the information on Google, so i'm asking here.
Is MySQL planning to implement CTE (Common Table Expression, with recursive query) and Window functions (row_number(), rank(), dense_rank(), lag(), etc..) ?

CTEs are defined in SQL:1999 standard.
Window functions are defined in SQL:2003 standard.

Those two functionnality are so usefull.. many query can't be written with MySQL due to this miss.
Every other RDBMS are implementing them now; PostgreSQL, SQL Server, Oracle...

So what's happening whith MySQL about that ?

I hope someone can answer.
Thanks,

PS: please excuse my English.
