Mike Dusenberry updated SYSTEMML-654:
-------------------------------------
Affects Version/s: SystemML 0.10
> DML Functions Should Override Builtin Functions
> -----------------------------------------------
>
> Key: SYSTEMML-654
> URL: https://issues.apache.org/jira/browse/SYSTEMML-654
> Project: SystemML
> Issue Type: Sub-task
> Affects Versions: SystemML 0.10
> Reporter: Mike Dusenberry
>
> Currently, if a user defines a DML-bodied function that has the same name as
> a builtin function, an error will be returned. This occurs both if the
> function is defined in the same file as it is being called (which could look
> like a builtin function call, although the user does not wish it to be), or
> if the function is defined in a separate file and called with a namespace
> notation. As we grow the language with an increasing number of builtin
> functions, this is not the desired behavior. Instead, any DML functions
> should override any builtin functions.
> Example 1:
> {code}
> min = function(int i) {
> print("hi" + i)
> }
> tmp = min(1) # fail!
> {code}
> Example 2:
> {code}
> # util.dml
> min = function(int i) {
> print("hi" + i)
> }
> {code}
> {code}
> source("util.dml") as util
> tmp = util::min(1) # fail!
> {code}
