[sqlite] There is any reason to sqlite not expand "*" in function calls ?

[sqlite-mail]

Hello !  

I'm testing the new json functions and when I tried this:  

select json_array(*) as json from one_table;  

I've got :  

[]  

[]  

..  

Then I tried with some custom functions accepting variable number of
parameters and realize that "*" is not expanded for function calls.  

There is any reason for it or it's a forgotten implementation ?  

Cheers !
