digitalmars.D.learn - DWT: synchronized toHash nothrow

So I've been wanting to switch to DTW from DFL, but that isn't 
too relevant. I though I could start with a update of the library 
for 2.059. This has ended up going into areas of synchronous and 
nothrow that I'm not as familiar.

I have hit

     public hash_t   toHash(){ synchronized(this){ return 
this.list.toHash(); } }

base\src\java\util\Collections.d(275): Error: _d_monitorenter is 
not nothrow
base\src\java\util\Collections.d(275): Error: function 
java.util.Collections.Collections.SynchronizedList.toHash 
'toHash' is nothrow yet may throw

ok, but what do I do. Does _d_monitorenter actually need to be 
nothrow so we can synchronize inside such functions?

On another note, I removed a bunch of "implMissing( __FILE__, 
__LINE__ );)" functions like toHash(). I think this is reasonable 
but thought I would ask.

Probably.

The workaround is: public hash_t toHash() { try synchronized (this) return this.list.toHash(); catch assert(false); } -- - Alex
