Both in fact as they are directly correlated.
The studies show that in high level languages (C nothwithstanding) there is
very evident but simple correlation -- number of programmer errors per
language construct (typically in not obfuscated code it's very close to the
number of not empty & non comment source lines) is independent of the
language. But languages do differ significantly wrt. how many constructs are
required to solve particular programming problems.
C++ (pre stl) was worst there, Python, Perl & likes were the best, Java was
not that bad but still about 30% worse thatn Python (C++ was 100% i.e 2x
worse). The biggest boost to effectivanes was bring by introducing automated
memory management (i.e. getting rid of explicit memory freeing). So even
languages with ugly C-ish syntax like "Perl the awful" can beat otherwise
elegant & clean languages. Hence probably the greaytest impact on Objective
Pascal productioveness would come from allowing programmers to declare
classes like self managing (self freeing, not needeing explicit destructions).
