question about go use

[sunxiao2010n]

In file cache.go

if !ok {
t = &CacheTable{
name: table,
items: make(map[interface{}]*CacheItem),
}

  mutex.Lock()
  cache[table] = t
  mutex.Unlock()

}

return t

the assigment function of cache item is

  t = &CacheTable{ ... }

The "t = &CacheTable" seems to be stored at stack , and can not be reentrant after function returns.
How could I understand this ?
Thanks.

t = &CacheTable
means
t = new CacheTable
