This is a small language feature which may improve the readability of the numeric values. It would be nice optionally allowing underscore characters in numeric literals such as:

int a = 1_000_000;
int b = 0xffff_ffff;
inc c = 0b0010_1101_1111_1010; // suppose Dart has binary literals

This is implemented in Java7 http://docs.oracle.com/javase/7/docs/technotes/guides/language/underscores-literals.html

There is issue #2873 for adding binary literals. When I was playing with their implementation in the VM, I also decided to implement this idea sometime in the future. I didn't yet get to it, but I'd also love to see this in Dart.

I guess we aren't going to implement every known feature in every language. This one doesn't seem to carry its weight.

Added WontFix label.

Revert "Bump pub."

This reverts commit 5c9e37f.

Reason for revert: flutter builds on golem somehow broke.
