Giampaolo can always change the licence of his work later. You can't 
take away the GPL from work you've already released, but you can 
relicense the same work under any other terms.

The problem may be if others have contributed to Giampaolo's library 
under the GPL, and they refuse to re-licence their contributions. I am 
not a lawyer, but it may be that he can work around that by requiring 
that contributors assign their copyright in the contribution to him. But 
that may discourage contributors.

But since Giampaolo seems to be thinking of using the MIT licence, the 
point may be moot :-)
