Proposal
Support binary integer literals. For example, the binary literal 0b00101010 would have the integer value 42.
Motivation
Several other major languages support binary integer literals, including Java (as of Java 7), Kotlin, Python and Rust.
Interactions with Other Language Features
Like other integer literals, binary integer literals support separators (_), which can greatly enhance the readability of larger values (e.g. 0b_1110_1101_1011_0111).
Implementation
The implementation of binary integer literals is quite simple, and can be found at https://github.com/scala/scala/pull/8275.
