I'm actually very intrigued by the idea of eliminating escape characters
altogether in the default string literals. Would follow nicely from how we
allow newlines in string literals. We'd have to give up the optional
"whitespace-chomping" behavior around newlines, though, which would make me
pretty sad. And are you really willing to force everyone who wants to
include a quotation mark in a string to go through a syntax extension to do
it?

People, please! Using delimiters on string literals is tantamount to
checking for null to determine when you've reached the end of a string in
memory. We've graduated beyond those barbarous days by explicitly noting
the length of each string in the header, so let's just reuse that idea!
Behold, Rust's new string literals:
fn main() {
print(#7"hello");
print(#2", ");
print(#5"world");
}
