Why no default property for TOracleQuery?

[jlcox]

Fields in TOracleQuery objects have to be explicitly called, i.e.,

Query1.Field('Somefield')

TOracleDataset and TOraclewwDataset allow

Query1['Somefield']

as do the native Delphi components. Why the discrepancy?

 

[Marco Kalter]

This has a historical reason. When we started developing Direct Oracle Access, compatibility with standard VCL components was not important to us. The TOracleQuery is not a TDataSet, and does not have any TFields, but is simply a low-level encapsulation of an Oracle Cursor.

That is understandable. However, even if it doesn't have any TFields, it acts as though it does through the Field property and in many ways emulates a dataset. So why can't it have a default property so that it behaves like other members of its (functional) type?
