Hello,

Please, could someone suggest a way to get "n" keys of a hash table? No 
order nor other restriction about the keys, just "n " keys existing in 
the table.

A method based on "iter" and raise and exception when limit is reached 
seems possible, but could be there are better options.

Thanks a lot.
