.gdc_list print output might be a bit misleading

Below, the files_list returned shows cases(8) which someone might interpret as 8 cases associated with the file. Not sure what the right answer is supposed to be, but in this particular instance, it is ambiguous what "cases" means. Should clarify.

> a = files(fields=grep('case',mapping('files')$fields,value=TRUE)[1:20])
> a[1]
class: files_list
files: 1

    5fc5ee74-3001-4deb-bfdf-b21695128a09

Will close this and focus efforts on #4.
