It's unspecified, so strictly speaking you cannot. (Also, everything in Go is passed by value). However, all well known Go compilers do put text literals into the text segment and one can reasonably expect the linker to coalesce them. The implementation of a string variable is a two worded struct having a pointer to the string value and the length of the string value. Only this struct is being passed around (by value), the actual value the struct points to never is. -- -j -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
