metadata should be exported to be usable by applications.
For teh API design a one test is that it should be possible to have a
dicom file as input and a format with similar features as output and not
loose any significant data.
Printing to the terminal cannot achieve that easily.
Either way i would suggest to support only a subset of these 4000 elements
for now but try to ensure that the deisgn can handle most of the important

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
