[Octave-bug-tracker] [bug #46553] Addpath shadows builtin functions without warning

[Philip Nienhuis]

Update of bug #46553 (project octave):

                Severity:              3 - Normal => 2 - Minor              
              Item Group:                   Other => Matlab Compatibility   
                  Status:                    None => Confirmed              
                 Release:                   4.0.0 => dev

Follow-up Comment #1:

Matlab (r2014a) does warn when paths added using addpath shadow builtins (I
tried with sin()), unlike Octave (also development version) => confirmed.

Note that str2double is a builtin in Octave but an .m-file function in Matlab
- hence your addpath() trick may work with Matlab (although I don't follow)
but not with Octave.

BTW, If I've interpreted your explanation correctly I would blame the creators
of your projects rather than The Mathworks. Shadowing core functions in
projects is rarely a Good Idea.
It is always possible to name functions along the lines of "str2double_1" or
"size_B"; at my work we have several "improved" Matlab functions named along
that principle.
As you're on Linux, a simple search & replace script recursing directories
could help you a lot.

I'll set Item Group to Matlab Compatibility and Severity to minor as there are
workarounds.
Status and Release also adapted.
