打字稿可變數量0.9.5

Question

我有這樣的情況下，該文件是t.ts：

interface Itest{ 
    (event: any, ...args: any[]):any; 
    } 

    var t1: Itest = function (testparam) { return true;}; 
    var t2: Itest = function (testparam, para1) { return true; }; 
    var t3: Itest = function (testparam, para1, para2) { return true; }; 


    interface Itest2 { 
    (event: any, para1,...args: any[]): any; 
    } 
    var t4: Itest2 = function (testparam, para1) { return true; }; 
    var t5: Itest2 = function (testparam, para1, para2) { return true; }; 

當我編譯這個與TSC 0.9.5我收到以下錯誤：

tsc --target ES5 "t.ts" 
t.ts(6,8): error TS2012: Cannot convert '(testparam: any, para1: any) => boolean' to 'Itest': 
    Call signatures of types '(testparam: any, para1: any) => boolean' and 'Itest' are incompatible: 
     Call signature expects 1 or fewer parameters. 
t.ts(7,8): error TS2012: Cannot convert '(testparam: any, para1: any, para2: any) => boolean' to 'Itest': 
    Call signatures of types '(testparam: any, para1: any, para2: any) => boolean' and 'Itest' are incompatible: 
     Call signature expects 1 or fewer parameters. 
t.ts(14,8): error TS2012: Cannot convert '(testparam: any, para1: any, para2: any) => boolean' to 'Itest2': 
    Call signatures of types '(testparam: any, para1: any, para2: any) => boolean' and 'Itest2' are incompatible: 
     Call signature expects 2 or fewer parameters. 

我錯過了什麼，或者這是壞的？它曾經在0.9.1.1中工作。謝謝！

由於其餘的參數是可選的，你需要讓他們在你的功能可選，以及：

interface Itest{ 
    (event: any, ...args: any[]):any; 
    } 

    var t1: Itest = function (testparam?) { return true;}; 
    var t2: Itest = function (testparam?, para1?) { return true; }; 
    var t3: Itest = function (testparam?, para1?, para2?) { return true; }; 


    interface Itest2 { 
    (event: any, para1,...args: any[]): any; 
    } 
    var t4: Itest2 = function (testparam, para1) { return true; }; 
    var t5: Itest2 = function (testparam, para1, para2?) { return true; }; 

這TS0.9.5
