Is that true? I don't claim to know exactly how the compiler 
works, but given a template lambda:

foo => 3

Doesn't it generate something like the following?

template __lambda10293(T)
{
     <deduced return type> __lambda10293(T foo)
     {
         return 3;
     }
}

In that case, "foo" is not a template parameter, but a runtime 
parameter, so template parameter introspection would not help in 
this case.
