Binary Literals - language feature

Example from Java, AspectJ, Pizza, Oracle Java, Deesel:

// 0[bB][01][01_]*[lL]?

// 0[bB][01]+n?
0b100110100000110011110010010

Example from Python, Cython:

# 0[bB](?:_?[01])+

Example from Perl:

# 0b[01]+(_[01]+)*

Example from MySQL:

-- b'[01]+'

Example from Swift:

// 0b[01_]+

Example from Haskell:

-- 0[bB]_*[01](_*[01])*

Example from Julia:

# 0b[01]+((_[01]+)+)?

Example from Prolog, CLPR, GAEA, Progol:

% 0b[01]+

Example from Elixir:

# 0b[01]+

Example from Verilog:

// ([0-9]+)|(\'b)[01]+

Example from Reason, MiniD, Croc:

// 0[bB][01][01_]*

Example from F#:

// 0[bB][01][01_]*[uU]?[yslLn]?

Example from Eiffel:

-- 0[bB][01]+

Example from D:

// 0[Bb][01_]+

Example from VHDL:

-- B"[01_]+"

Example from Chapel:

// 0[bB][01]+

Example from Monkey:

' \%[10]+

Example from Ceylon:

// \$([01]{4})(_[01]{4})+

Example from SystemVerilog:

// ([1-9][_0-9]*)?\s*\'[sS]?[bB]\s*[xXzZ?01][_xXzZ?01]*

Example from C3:

0b110011

Example from Speedie:

|| num = 0b010101

Example from K:

/ [01]+b

Example from Felix:

// 0[Bb][01_]+([tTsSiIlLvV]|ll|LL|([iIuU])(8|16|32|64))?

Example from Jule:

0b0001010101

Example from Whiley:

// [01]+b

Example from Aardvark:

`2_101` would evaluate as a binary number.
