I think both sides of that case can be well argued, tho I fall on
your side.  Design is all very well and good if the implementation
sucks.  To the extent that the language attempts to enforce a
particular implementation pattern, and that pattern is in agreement
with the base design, then yes, this is easier and helpful.  You let
the language definition do some of the interpretation of the design
for you.

This is BTW one of my main complaints with perl, a language I've
come to increasingly dislike: It attempts to impose absolutely no
concepts of correctness or enforced pattern on its users and thus
leaves all all higher level structural definitions to ad-hoc
per-user per-case definition.  Uber-flexible to be sure, but I
challenge anybody to either:

  a) Write an BNF for perl

or,

  b) Implement a matching independent implementation of the
     language.
