Details:

In Matlab the following is legal:


>> 1 ++1

ans =

     2.0000e+000
>> 1 + +1

ans =

     2.0000e+000
>> 1 ++ 1

ans =

     2.0000e+000


But in Octave it the first is an error:


>> 1 ++1
parse error:

  syntax error

>> 1 + + 1
ans =  2

>> 1 ++ 1
parse error:

  syntax error



I couldn't find this on the bug tracker, but it's difficult to search for.
Perhaps it is known and thought not worth fixing given the simple workaround.
I only discovered it in my own code due to a typo.
