// This file is based on the example JavaScript grammar that comes with PEGJS.
// https://github.com/dmajda/pegjs/blob/master/examples/javascript.pegjs
//
// Grammar spec:
// This is a small subset of JavaScript.
// - Only the expression grammar is included (i.e. no statements or any other
//   larger grammar constructs).
// - No newlines or comments (but whitespaces are fine).
// - No assignment operators (including increment and decrement).
// - No comma operator.
// - No Array and Object type (literals as well as look up).
// - No bit-wise operators.
// - The operator precedence is same as that of JavaScript.
//
// Parser output:
// The parse tree is made of arrays and JavaScript's primitives, i.e. booleans,
// numbers, strings, and nulls (but not undefineds).
// Each node of the tree is an array, representing the operation performed for
// that node. The first element of the array is the operator name, and the rest
// are the parameters for that operator (i.e. polish notation).
// Most operators have the same textual name as in the corresponding input
// grammar, e.g. logical or operator is "||". This is the same for function
// calls, e.g. "abs(-30)" will be represented as ['abs', -30].
// "#" is a special operator for parameter value look up (with one argument
// which is the parameter name).
// The difference of unary and binary '+' and '-' need to be infered by the
// number of arguments.
