示例1: withFunKind

// TODO:ES6 use `...`f
const nArgs = new LiteralNumber(args.length)
const opDeclareRest = opMap(opRestArg, rest =>
makeDeclare(rest, new CallExpression(arraySliceCall, [idArguments, nArgs])))
const argChecks = opIf(compileOptions.checks, () =>
flatMapOps(args, opTypeCheckForLocalDeclare))
const opDeclareThisAst = opIf(opDeclareThis !== null && !dontDeclareThis, () =>
declareLexicalThis)
const lead = cat(opDeclareRest, opDeclareThisAst, argChecks, leadStatements)
const body = () => transpileBlock(block, {lead, opReturnType})
const argAsts = args.map(transpileLocalDeclare)
const id = opMap(verifyResults.opName(_), identifier)

return id === null && opDeclareThis === null && opDeclareRest === null ?
new ArrowFunctionExpression(argAsts, body()) :

})示例2: opIf
return opIf(!localDeclare.isLazy, () =>
opMap(localDeclare.opType, type =>
new ExpressionStatement(msCall(
'checkInstance',
transpileVal(type),
accessLocalDeclare(localDeclare),

export function transpileYieldLikeNoLoc(_: YieldLike): Expression {
if (_ instanceof Yield)
return new YieldExpression(opMap(_.opValue, transpileVal))
else if (_ instanceof YieldTo)
return new YieldDelegateExpression(transpileVal(_.value))

}示例4: parseClassHeader
function parseClassHeader(tokens: Tokens)

})),

traits: caseOp(traitTokens, parseExprParts, () => [])
}
}示例5: opKeywordFromName
export function opKeywordFromName(loc: Loc, name: string): Op<Keyword> {
// I tried a switch statement, but using a map of closures was actually faster.
return opMap(nameToKeywordCreator.get(name), _ => _(loc))
}示例6: parseCase
export default function parseCase(tokens: Tokens): Case {
const [before, block] = beforeAndBlock(tokens)
const opCased = opMap(opParseExpr(before), _ => AssignSingle.focus(_.loc, _))
const {parts, opElse} = parseCaseParts(block)
return new Case(tokens.loc, opCased, parts, opElse)
