User Defined Inline Scalar Valued Functions
Please allow the option of creating true inline user defined scalar valued functions.
The current workaround is to use inline table valued functions that produce a scalar value, however, the syntax for accessing iTVF is different than the syntax used for scalar functions. This makes if time consuming (and in some cases impossible) to replace poor performing scalar functions with a more performant iTVF version.
