One version for C (or C++) is a thing of beauty. It's a bit
inconvenient since you need to put the string in the middle of the

gcc -o /tmp/run -x c - <<< '#include <stdio.h>
int main() { printf("hello, world\n"); }' && /tmp/run
Good point. gcc comes close here!
Go currently allows
echo 'package main; func main() {println("Hello, world!")}' > hello.go; go
run hello.go; rm hello.go
but following gcc's example would let us shorten that to
echo 'package main; func main() {println("Hello, world!")}' | go run -
