				For the &quot;generics&quot; version ... I don't think the current way of parameterisation is suitable here.<br />
<br />
1)<br />
In the current way, one can only semantically check a construct once it is used with an actual parameter.<br />
This would mean, that it is not possible to ensure that libraries are safe, without trying for all possible types.<br />
<br />
2)<br />
As each actual instance (with for example an actual type parameter) has to be checked, that would lead to an explosion in semantic checking duration.<br />
Just think of not checking the hashmap only once, but once for each and every time it is instantiated (maybe even used)<br />
<br />
3)<br />
To solve the above problems, we would need some kind of type-erasure logic ... which does not yet exists in the advanced parameterisation.<br />
Or concepts (with which C++ has been strugling in the last few decades)			</td>
