More of a Sea++ of errors, it reminds me of Another Language.
It's because ScopeExp::semantic() doesn't use template instances if
global.errors is true.

Test case (not reduced, relies on D2 Phobos where writefln is a template):

import std.stdio;

T[] findroot(T)(in T x)
{
   writefln("xxx");
}

void main()
{
   findroot(1.0L);
}
