There are two forms of import statements. All imports of both forms are interpreted simultaneously: their order doesn't matter.
IMPORT I AS Jwhich imports the interface whose global name is I and gives it the local name J. The entities and revelations declared in I become accessible in the importing module or interface, but the entities and revelations imported into I do not. To refer to the entity declared with name N in the interface I, the importer must use the qualified identifier J.N.
The statement IMPORT I is short for IMPORT I AS I.
The second form is
FROM I IMPORT Nwhich introduces N as the local name for the entity declared as N in the interface I. A local binding for I takes precedence over a global binding. For example,
IMPORT I AS J, J AS I; FROM I IMPORT Nsimultaneously introduces local names J, I, and N for the entities whose global names are I, J, and J.N, respectively.
It is illegal to use the same local name twice:
IMPORT J AS I, K AS I;is a static error, even if J and K are the same.
