各个类型的value部分，进行copy所需要的字节数
关于各个类型部分内置function部分的
ways to concatenate strings
+ 少于6个strings推荐使用
strings.Join方法
fmt.Sprintf以及fmt.Sprint
Buffer方法？
ways to block current goroutine forever
select{}<-chan struct{}(nil)send value to a channel which no ones will receive values from
make(chan struct{}) <- struct{}{}- receive from a channel which no values will be sent to
<-make(chan struct{})
Expressions which can return an optional additional bool return value
包括三类
map
channel
type assertion
Types which don’t support comparisons
map
slice
function
struct types containing incomparable fields
array types with incomparable elements
Values that can taken addresses
variables
fields of addressable structs
elements of addressable arrays
elements of any slices (whether the slices are addressable or not)
pointer dereference operations
Values that can’t taken addresses
bytes in strings
map elements(?)
dynamic values of interface values (exposed by type assertions)
constant values
literal values
package level functions (这个试验一下)
methods (used as function values)
intermediate values
Types which zero values can be represented with nil
这里列举一些
nil所需要的字节数Type (T) Size Of T(nil) pointer 1 word slice 3 words map 1 word channel 1 word function 1 word interface 2 words
