Details:

In version 3.6.4


octave:1> str = "1a"
str = 1a
octave:2> x.(str) = 1
error: invalid structure field name '1a'


in version 3.8.2 and all later versions


octave:1> str = "1a"
str = 1a
octave:2> x.(str) = 1
x =

  scalar structure containing the fields:

    1a =  1


The dynamically created field name for the struct is no longer validated that
it is an appropriate variable name.  This is a problem because it is then
rather difficult to get the value from the structure because the parser emits
an error.  If the struct is saved, the file will no longer load back because
load() detects that the fieldname is invalid.


octave:5> x.1a
parse error:

  syntax error

>>> x.1a
