Nested batch for loops

Question

The following nested for-loop drives me mad (on Windows 7):

@echo off
SetLocal EnableDelayedExpansion

set TESTDIRS=fast mid slow
set TD=src\\test\\resources

Quote Malte Schwerhoff's Answer

If you don't want to repeat B, you can simply add "if" statement

@echo off
SetLocal

set B=alpha beta gamma
set A=eins zwo

FOR %%b in (%B%) do (
  FOR %%a in (%A% %%b) DO (
    IF %%b NEQ %%a (
        echo %%b -^> %%a
    )
  )
)

output:

alpha -> eins
alpha -> zwo
beta -> eins
beta -> zwo
gamma -> eins
gamma -> zwo
