Maybe I'm missing something obvious, but why do you need to do this? Seems like some sort of remote dependency injection which requires you to serialize code from the server to the client. Why not just release a compiled client binary which has all of the implementations compiled in already,

The immediate goes first, like this: SHUFPD $1, X1, X2 Note that SHUFPD takes an immediate for the shuffle - I don't see how you can implement the function you want; it takes a dynamic shuffle argument. Unless you do a switch on all possible values of the immediate. On Tuesday, June 13, 2017

Well -- I was wrong. I got it backwards. There is a String() function is a receiver for *http.Cookie so it gets called when you need a string representation of a *http.Cookie (pointer to http.Cookie). On Wed, Jun 14, 2017 at 1:18 PM, Aman Kapoor wrote: > Hi Ayan, > >

Hi Aman -- When you print *http.Cookie, Go does it's best to print each field knowing that it is a pointer to a struct. This is the format you end up with. But http.Cookie has a String() method associated with it that provides the output that you get when you simply print 'cookie' (without the
