Regarding Steven's example, like Sven, I also see it this way:

    [*t for t in [(1, 'a'), (2, 'b'), (3, 'c')]] 

should mean:

   [*(1, 'a'), *(2, 'b'), *(3, 'c')]] 

Which coincides with what the OP is asking for.

From a CPython implementation standpoint, we specifically blocked this code path, and it is only a matter of unblocking it if we want to support this.
