Make "variable templates" output a constant size array instead of a slice.

[xzores]

I would like to be able to #unroll the following loop:

my_func :: proc($something : ..string){
    
    #unroll for a in something {
        //something that requires a to be compile time constant.
    }
}

I get the error:

Error: Cannot iterate over 'something ' of type '[]string' in an '#unroll for' statement
        #unroll for a in something 

Request:
Make it return an [N]string instead of a []string. It would allow to do more stuff in compile time and hence catch errors earlier.
