I think this test is incorrect. It should be ints => query

The test is correct when based on the assumption that every nested IQueryable reference encountered should be also decompiled (I suppose that is the issue you raised by your comment that decompilation may go to far ?)
The test will fail anyway because of different outputs, but the difference would be acceptable (System.Int32[] instead of the expected Empty().AsQueryable())

I've fixed majority of the cases except EF tests. Also, it seems that decompilation here is going too far and maybe undesirable for some users. |

The nesting handling is so simple that I did not see it sitting right in front of me
I suppose you're talking about the fact that the solution provided here assumes that any |

@hazzik rebased and I restricted dereferencing queryables only to explicitly decompiled instances (also applied this to the EF tests) |

Can you add test where the query would not be decompiled

Hi @hazzik, got a bit sidetracked.
I'm not sure I understand what test you want added here, so I added one failing test to expose the issue and refactored the other to compare materialized results

@hazzik
here's PR #209 merged directly into OtpimzeExpressionVisitor.cs
Once again, I committed the unit tests first for demonstration.
