CQL Fluent Functions Overload function name

[SeenaFa]

When overloading a fluent function, using the same function name but different arguments, it seems that the order in which the functions appear in the CQL library matters.

Below is an example showing how you get different results when ordering the fluent functions:

`library IssueFluentFunctions

using FHIR version '4.0.1'

context Patient

define "EobFluentFunctionError": ([ExplanationOfBenefit]).ffoverload()

define fluent function ffoverload(eob List):
eob.item.serviced.value

define fluent function ffoverload(obs List):
obs.effective.value

////////////////////////////////////////////////////////////////////////////////////

define "EobFluentFunctionError2": ([ExplanationOfBenefit]).ffoverload2()

define fluent function ffoverload2(obs List):
obs.effective.value

define fluent function ffoverload2(eob List):
eob.item.serviced.value`

The results are as follows:

Patient=Patient(id=SamplePatient1)
EobFluentFunctionError=[]
EobFluentFunctionError2=[2023-03-31]

Not sure what the expected behavior is but the expected result is that the date should be returned for both.
