I'm with Robert on this one.
If a language is designed with a simple, consistent syntax then it is
not only easier for the compiler to parse, but (more importantly) it
is easier for humans to understand and therefore easier to get
right. Can you guess I like Pascal, which was designed from the outset
for a single pass RDP?
I'm no expert in these matters (then shut-up, they cried), but it
seems to me that to express complex ideas we need a rich vocabulary,
but not a complex syntax. And if not, then why do we do it?
Why make anything needlessly complicated? Just to prove how clever we are?
Human languages are too ambiguous for programming. They only work for
humans because we add redundant information, use context to resolve
ambiguities, or simply make assumptions (which sometimes/often turn
Human languages are complex and ambiguous not because we like them that
way, but because they have evolved from something simple. Like C++ :-)
Finally, if you want to program in a human language, try parsing this old
