[Octave-bug-tracker] [bug #40613] exist(..., 'var') slow when variable does not exist

[Michael Goffioul]

Follow-up Comment #2, bug #40613 (project octave):

I think this is down to the implementation. When looking at the code, it
appears octave is looking for the symbol named NAME, then check that the
symbol found is of type TYPE. In that regard, supplying the type argument does
not offer any speedup.

Because a symbol can be many different things, when a symbol does not exist as
a variable, octave will try hard to find the matching symbol: functions,
methods... and if nothing is found, it'll refresh path and start again.
