Using local imports is dangerous. It should be used only with
selective imports
Some of these problems can be avoided when you write good code.
Explicit import is allowed but not the best especially when you
are just using one or two functions (locally or globally).
Same as those who write:
class Name {
string name;
this(string name) {
name = name;
}
}
Instead of;
class Name {
string name;
this(string name) {
this.name = name;
}
}
Imagine you have;
class Name {
string realName;
this(string name) {
.... a lot of code here.......
string realName = name ..... //This will punish you
.... a lot of code here.......
string finalName = realName .......
.... a lot of code here.......
realName = finalName; // code maintained for a long time
}
}
Writing good code takes time much like mining diamond.
