Issue ID: 23655
Summary: __traits(toType) shatters modularity
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P2
Component: dmd

This might not technically be a bug since the spec says "a type that has been
seen by the implementation" but this is is a bad feature regardless.
```
struct S {};
alias t = __traits(toType, "S6totype1S");
```
then make a totype.d with `struct S {}`
compile:
$ dmd totype2.d
totype2.d(3): Error: cannot determine `__traits(toType, "S6totype1S")`
then compile:
$ dmd totype.d totype2.d
fine!
then compile:
$ dmd totype2.d totype.d
totype2.d(3): Error: cannot determine `__traits(toType, "S6totype1S")`
D has very few features that cross modules like this and they're bad to have.
We should start removing these things, especially when they are unused and
unnecessary, to remove potential for more serious order of eval bugs arising
from them.
