I take issue with almost all of the above!
On ease of typing, I fail to see how typing "}" can possibly be slower than typing e.g. "End If", especially when including wasted time relocating the cursor to correct typos.
On spotting errors, I fail to see how a missing "}" can be easier to spot than a missing "End If". The eye automatically matches bracket pairs, whereas matching "If", "End If" is far harder.
On the comparison with English, note that English can be pretty punctuation heavy when conveying complex concepts, and all the better for it. Compare the following:
> "When you wake up in the morning, Pooh," said Piglet at last, "what's the first thing you say to yourself?"
"What's for breakfast?" said Pooh. "What do you say, Piglet?"
"I say, I wonder what's going to happen exciting today?" said Piglet.
Pooh nodded thoughtfully. "It's the same thing," he said.
