Random question, why would someone use gccgo over the standard go compiler?
with gccgo you get to take advantage of a lot of gcc's optimizations (-O3) and it can generate faster code because of it.

I really wish they'd add string interpolation to Go. After being able to use s"My name is $name and surname is $surname" in Scala and "My name is #{name} and surname is #{surname}" in Ruby I find working with printf a giant step backwards.
I wish they didn't! Magic features like this belong to magic languages like Ruby. Go is not meant to be a magic language.
String interpolation is both practical and useful.

One reason is that gccgo supports many architectures that gc does not (SPARC, MIPS, PowerPC, Alpha). It also was the only way to get Go on Solaris until the more recent port of gc to that platform. gccgo is also supposed to produce better code for certain computationally heavy workloads.
Unfortunately, this is very seldom true. Gccgo could potentially generate faster floating point code, but its lack of escape analysis grinds it to a halt.
If Go is coming to Native Client, then perhaps it will come to Android, too?
Cross compilation of programs using cgo? I thought that was landing in 1.3 as well

Go is designed to be a very practical and productive language. It's not quite clear how you're defining "magic" ... String interpolation is both practical and useful.
It's the kind of feature that is useful when you write an application but not that useful when you're trying to debug it.

String interpolation is magic because it's not entirely obvious when it happens, what scope rules are followed, if there are any side effects, if the original string is overwritten or whether a new instance is created, what happens when they are used within bodies of loops, what happens when they are used within closures etc., it just works. Sure these can be specified explicitly but they aren't obvious. It's the kin…
It's largely used in log messages and the like where it's used for debugging issues after the fact. I've yet to encounter a case where anyone was ever confused by the behaviour.

"My name is #{name} and surname is #{surname}"
"My name is " + name + " and surname is " + surname
fmt.Println("My name is %s and surname is %s", name, surname)
String interpolation seems like a small thing, but I find myself wanting to use it all the time. It's definitely not a "magic" feature. Javascript really needs it as well.

How are we on IDE's? Last time I tried go (over a year ago) I couldn't really find a nice IDE.
