Incorrect evaluation occurs when a local variable name collides with the template argument of an instantiated template parameter.

[AkiSakurai]

struct array<auto count> {
    u32 value [count];
};


struct root<type> {
    u8 size; 
    type a;
};


u8 size@1;

using a1 = array<size>;
root<a1> rot @ 0;

The template parameter size in array should refer to the template argument, not the local variable inside root struct.
