You can, however, do something along the lines of:

my $sql = '... WHERE foo IN (' . join(',', ('?') x scalar( @values ) +) . ') ...';

in order to generate the proper placeholder-based statement that you can then pass your parameters into.

See also DBIx::PreQL.

Update: As per BrowserUK (below), in order to make use of this, you either need to prepare your query each time, cache your prepared query based on number of parameters using prepare_cached or some other method, or know that the number of parameters will be the same each and every time.
