The idea of LINQ is that you write the expression directly in the language and it translates into a query expression. It's going to be operating on an expression parse tree, right? Rather than trying to change the allowable expressions maybe the question is to figure out how to translate what we have and find what we can't express with what we have (and that's an orthogonal question and has nothing to do with xxx functions).

Isn't there are already a syntax for this? expr = lambda: x + y * z Maybe you want some conversion of that lambda into a different form: expr = @ast lambda: x + y + z Or:

 results = db => sql_expression

where the parse tree for "sql_expression" is passed to db.linq.

The parse tree is compiled to SQL and cached for possible future use.
