## Expressions

An expression specifies the computation of a value by applying operators and functions to operands.

### Operands

Operands denote the elementary values in an expression. An operand may be a literal, a (possibly [qualified]()) non-[blank](#blank-identifier) identifier denoting a [constant](#constant-declarations), [variable](#variable-declarations), or [function](#function-declarations), or a parenthesized expression.

```go
Operand = Literal | OperandName [ TypeArgs ] | "(" Expression ")" .
Literal = BasicLit | CompositeLit | FunctionLit .
BasicLit = int_lit | float_lit | imaginary_lit | rune_lit | string_lit .
OperandName = identifier | QualifiedIdent .
```

The [blank identifier](#blank-identifier) may appear as an operand only on the left-hand side of an [assignment statement](#assignment-statements).
