If the writelns are uncommented out, get a FileException

So what I've been using is a feature of the compiler that prints
out a string representation of the AST. This is the `-vcg-ast`
switch.
Looking at that, the catch clauses for `FileException` and
`Exception` are missing when `writeln` is in the loop.
I have also discovered that it's not specific to writeln, and
that *any* throwing (or possibly throwing) function will do.
For example:
```d
void foo() {} // not nothrow
void fooNothrow() nothrow {}
// this will catch the FileException:
try
{
foo();
if (entry.isDir)
scan(entry.name);
}
// this will catch the Throwable:
try
{
fooNothrow();
if (entry.isDir)
scan(entry.name);
}
```
Clearly, the compiler is misjudging this code as nothrow.
I think I can get a small reproducible example that does not need
all the extra complication. But need some time to narrow it down.
