It doesn't seem to add power to the language. "static try" would be way 
better because a typical idiom is:

static if (__traits(compiles, { codecodecode }))
{
     codecodecode
}

It would be way nicer if we had something like:

static try
{
     codecodecode
}
catch (Exception e)
{
     // e.msg contains the compile-time error
}
