When using expect() for writing asserting, some of the assertion are using properties as the mean for calling assert.

For example

expect(foo).to.exist

JSLint/JSHint will complain about such code, since it expects an assignment or function call.

Hiding a function call, behind getting a property can be sweet but in tests, it leads to such warnings.

I know that one can use assert calls, or not use JSHint/JSLint or configure JSHint/JSLint to ignore such warnings, but I just want to know what is your feeling about this problem.
