The implementation of ranges for case-conditions are not failings.

They are not 'banned' by the first Pascal standard, and their absence is not
due to technical considerations - it is just a matter of historical timing.
The Case statement was a recent programming language invention by Tony Hoare
when Pascal was originally conceived in 1968. The use of case-label ranges
wasn't proposed until 1974 by which time Wirth had already started working
on Modula. Case-label ranges were eventually included in the Extended Pascal
ISO Standard 10206:1990. Wirth's later languages (including Modula-2 and
Oberon) both included case-label ranges from day 1. He does not have a
reputation for introducing error-prone or inefficient features on a whim -
just the opposite in fact.
