Don't wrap import() expression

Source:

export function moduleLoadCallback() {
    return import(/* webpackChunkName: "a" */ "./a.module")
        .then(function (module) { return module.A; });
}

TS Out:

export function moduleLoadCallback() {
    return import(/* webpackChunkName: "a" */ "./a.module")
        .then(function (module) { return module.A; });
}

TsickleOut:

export function moduleLoadCallback() {
    return (import)(/* webpackChunkName: "a" */ "./a.module")
        .then(function (module) { return module.A; });
}

angular 5 no longer produces generated .ts code, it is all compiled in one pass. this is because we now use a better architecture with TypeScript transformers. There is no option to go back to .ts codegen.

It sounds like using annotationsAs: "decorators" might be a workaround for you?

I agree that tsickle processing shouldn’t wrap the import keyword in parens.

Angular use now import() for lazy load so this seems fixed now
