Generating switch at Compile Time

[Jesse Phillips via Digitalmars-d-learn]

I realize that this is likely really pushing the compile time 
generation but a recent change to the switch statement[1] is 
surfacing because of this usage.

uninitswitch2.d(13): Deprecation: 'switch' skips declaration of 
variable uninits
witch2.main.li at uninitswitch2.d(14)

---------------------
     import std.traits;
     import std.typecons;
     import std.meta;

     private static immutable list = AliasSeq!(
             tuple("a", "q"),
             tuple("b", "r"),
             );

     void main() {
         import std.stdio;
         string search;
         switch(search) {
--->        foreach(li; list) { // li initialization is skipped
                 mixin("case li[0]:");
                 mixin("writeln(li[1]);");
                 return;
             }
             default:
             break;
         }

         // Works
         mixin(genSwitch("search"));
     }
---------------------

I realize I can build out the entire switch and mix it in:

---------------------
     string genSwitch(string search) {
         auto ans = "switch(" ~ search ~ ") {\n";
             foreach(li; list) {
                 ans ~= "case \"" ~ li[0] ~ "\":\n";
                 ans ~= "writeln(\"" ~ li[1] ~ "\");\n";
                 ans ~= "return;\n";
             }
             ans ~= "default:\n";
             ans ~= "break;\n";
         ans ~= "}";

         return ans;
     }
---------------------

But I'm just wondering if the new initialization check should not 
be triggered from this utilization.

                 writeln(param0[1]);
                 return;
             }
             {
                 case param1[0]:
                 writeln(param1[1]);
                 return;
             }
         }
     }
