[Octave-bug-tracker] [bug #29476] Parser incompatibility for keywords against Matlab implementation, infinite loop

[Paul Ortyl]

Follow-up Comment #2, bug #29476 (project octave):

In short: Matlab (tested with R2008a) accepts the code and runs it
correctly.

In the example, which is boiled down version of legacy module I have to use
an cannot modify, the 'do' is in context of definition of function
'prototype'.  In this context, forced by keyword 'function', these two letters
'do' cannot be keyword 'do' from the do...until loop.  It means that a
function named 'do' can be created overriding the keyword 'do'.  It has the
consequence, that no do...until loop may be used in this file.  As long as the
language 'specification' does not prohibit overriding of keywords the code is
correct.  Taken, that the reference implementation is Matlab(R) then the
masking of keyword by function name is allowed.

I must admit, that the concept of defining function with name theoretically
'reserved' to keyword is scary idea... but Matlab does not prohibit that.

I would expect this 'functionality' to work at least in --traditional mode.
