Thanks, I'm fully aware of this! :)

My initial plan was to patch B::Deparse in a way to take the op-tree of the code-block and to produce SQL instead of Perl (or rather a semantically correct intermediate Perl representation which produces SQL)

> flattening of "(" and ")"

likewise, true lists are flattened but precedence is still visible in the op-tree

BUT for the moment I'm rather inclined to create subs OR() and AND() for a quick prototype.

That is taking multiple expressions after a prefixed operator. 

 
WHERE {
   OR ( number EQ 3, 
        AND ( 
            customer LIKE '%...%',
            name     IN   qw/John Jane/,  
        )
      )
}

Thats not really much overhead, because when mixing AND and OR parens should always be applied to highlight precedence.

I'm very busy ATM but I'll show a proof of concept after next weekend.
