First there was a typo:
it should read
operator T() const
not
operator T&() const

Of course I want to avoid this, but could you please be more specific?
Is it the
static_cast<T>(*data)
that will cause troubles?
If so why?
Would it be better to use something like
operator T() const
{
T t = 0;
for (unsigned n=0; n<sizeof(T); ++n)
{
t |= ((T)data[n])<<(8*n);
}
return t;
}
