[Octave-bug-tracker] [bug #48064] for-loop over structure elements behaves differently from document

[Lachlan Andrew]

Follow-up Comment #1, bug #48064 (project octave):

Matlab (R32013b) doesn't implement this feature, so we are not bound by
compatibility issues.

My preference would be to change the documentation to
"Either the key or val variable may be replaced by a tilde."
or perhaps allowing only "[val]", but still making the brackets mandatory.

The alternative (making brackets optional) would require run-time processing
to determine whether the RHS is a structure or an array, which would slow down
the common case for a minor syntactic advantage in the (very?) rare case.
