Binary Operators
The following binary operators supported:
Arithmetic Operators  

* 
× (U+00D7) 
⋅ (U+22C5) 
Multiplication. Returns the product of numeric operands. Can be overridden. 
/ 
÷ (U+00F7) 
∕ (U+2215) 
Division. Returns the quotient of numeric operands. Can be overridden. 
+ 
Addition. Returns the sum of numeric operands. Can be overridden.  
 
− (U+2212) 
Subtraction. Returns the difference of numeric operands. Can be overridden. 
Comparison Operators  

== 
Equals. Returns true if operands are equal, or false otherwise. Equality check algorithm can be customized. 

<> 
≠ (U+2260) 
Not equals. Returns false if operands are not equal, or false otherwise. Can be customized together with == operator. 
<=> 
Compare. Compares operands. The result of comparison may have arbitrary type. Comparison algorithm can be customized.  
> 
Greater than. Returns true if the left operand is greater than the right one, or false otherwise. Can be customized together with <=> operator. 

>= 
≥ (U+2265) 
Greater than or equal to. Returns true if the left operand is greater than or equal to the right one, or false otherwise. Can be customized together with <=> operator. 
< 
Less than. Returns true if the left operand is less than the right one, or false otherwise. Can be customized together with <=> operator. 

<= 
≤ (U+2264) 
Less than or equal to. Returns true if the left operand is less than or equal to the right one, or false otherwise. Can be customized together with <=> operator. 
Special Operator  

~ 
Suffix. A special operator capable of representing things such as quantities, like 3~minutes . Can be customized. 
Note, that the right operand should be at the same line with the left operand and operator sign. The following code will raise a compile time error:
1 + ~~ Right operand expected here. 2
While the following code will not be interpreted as a binary operator:
1 ~~ First statement. + 2 ~~ Second statement.
An underscore should be used to place the binary operator on multiple lines:
~~ Place an underscore on the next line (__recommended practice__). 1 + _2 ~~ Place an underscore before the sign. 1 _+ 2
Operators Precedence
Binary operators has lower precedence than unary operators and reference qualifiers.
