Also, there doesn't seem to be much use of regular expressions.
Well, I guess Pascal programmers prefer readability over shortness.
They're definitely not a panacea, but where you want to do things like
extract the x.y.z version number from e.g 'PostgreSQL 8.4.6 on
i686-pc-linux-gnu, compiled by GCC 2.95.3, 32-bit' and 'LI-V2.5.0.26054
Firebird 2.5 Release Candidate 3', using regexes can end up being more
readable provided that the comments include examples of what should be
matched.
I know that function and variable names should be chosen so as to reduce
the need for comments, but I feel that large sections of the programming
industry are still biased against them because they have this fixed idea
that they introduce overhead in the generated code or can give away
trade secrets to the end user. In short, we're still hobbled by the
legacy of interpreted BASIC, which is about all that some management
types know.
