syntax sugar for conditional check

Hello,

I thought it would be cool to have conditional check syntax, which gets converted to simple check constraint syntax.

Here’s a gist:

It’s just sugar, but i think it would make check constraints easier to read, and easier to write without backwards boolean logic.

Thank you,

AJ
