Grouping Conditionals - where (a and b) or (c and d)

[jwsample]

Is there a way to group conditional logic?

For example:

select * from table
WHERE
 ( a = 1 AND b = 2)
OR
 (c = 3 AND (d = 4 and e = 5))

In my experimentation so far it seems like all the conditions get flattened and can't be nested.
It doesn't look like you can pass And() querymods into an Or() /Where() for example. I realize in this simple example it can be straight sql passed in, but beyond one level of nested logic there would be quite a bit of string manipulation.
Whats the sqlboiler way of doing this?

Well, never mind. Looks Expr() is exactly what I was looking for. I swear I read that section of the docs a hundred times and kept missing it.

I'll leave this question here in case someone else searches the question the way I did.
