[R] foreign read.S

When I convert an S-Plus 2000 binary list object to R using read.S in the foreign package, elements of the list that have 'names' attributes are sometimes set up to have '.Names' attributes.  I suppose that S-Plus had used .Names invisibly to me.  Does anyone have code to recursively go through a complex list efficiently and change all '.Names' attributes to 'names'?  I tried just doing this with dput or dump and Emacs but the list contains some expressions that dget or source tries to evaluate that do not make sense at that stage.

Perhaps read.S could be enhanced to do this automatically.
