Built-in functions and UDFs

Hi all,

Currently, the usage of UDFs is restricted to simply being able to call the UDF and assign the results to a variable.  If the user wishes to use the UDF as input to a built-in op of any sort on the same line, an error is thrown.  This is confusing for users, and leads to messy code involving temporary variables.

Here is a simple example that does not work, yet should:

    out = my_udf_func(x) + 4


Can we please fix this?  UDFs should be treated like any other op.

Thanks,

- Mike
