I'd love to check whether a string value is the name of a type 
at run-time.

E.g.:


string a = "int";
string b = "im no type";
assert( isStringType(a) );
assert( !isStringType(b) );

or

struct TestStruct
{
     int test;
}

string t = "TestStruct";
assert( isStringType(t) );


Is anything like this possible?

The goal is to identify whether a string represents a custom 
type within a package. I'm also trying to iterate over all 
modules within the package to get the struct name. However, 
that seems like a struggle...

Any ideas?..

In order to do this, the list of types must be stored somewhere 
to compare with at runtime.

At this time, this is not done. You could potentially do this 
with the RTInfo template, but it would have to be part of a 
custom druntime.

Thanks Steve!
That's sound too much of a strugge for a newbie like me : D. I'll 
probably evaluate and compare the type names as strings then and 
derive further processing from there.
