using string as cell selectors

[CdeMills]

Hello,

the dataframe class nearly passes all tests under 3.3.52+. The last problem
is a failure in expressions like
x.types{"Freq"} = 'uint32'

The logic behind it is: x.types is of class 'cell', we should be able to
select by column name.

Under 3.2.4, the last part of S contains the string "Freq" in the field
"subs". Under 3.3.52+, it fails with 'invalid assignement to cs-list outside
multiple assignment".

I checked under MatLab, the behaviour is to use the ascii code of chars as
selectors: x.type{1} refers to the 49th value, and so on. So x.type{'Freq'}
should refer to 4 values. This mechanism is also used in parenthesis
derefencing. The only way in MatLab to have a selector as string is in
x.('some string')

Should we follow this path, or accept to have strings as element selectors
everywhere ? If we go on the first hypothesis, how to translate actual
expressions like
x(1, "Freq")
x.types{"Freq"}

Regards

Pascal
