mixin parsing as expression

[NCrashed]

I am a big fan of playing around with mixins, I found that following code is valid for compiler and fails at DDT parser:

import std.conv;

int val1;

string getVal(size_t i)
{
    return text("val",i); 
}

void main()
{
    mixin(getVal(1)) = 10; // Multiple markers at this line
//  - Unexpected token "=", while trying to parse 
//   Statement.
//  - Syntax error on token ")", expected SEMICOLON 
//   after.
}
