I would argue that the following snippet of code should either print
"CAT" twice or die. Unfortunately it first prints "DOG" and then "CAT".
Thanks,

MACRO(FOO BAR)
SET (BAR "CAT")
MESSAGE("${BAR}")
ENDMACRO(FOO)
FOO(DOG)
MESSAGE("${BAR}")
So, expand the macro and you get:
SET(BAR "CAT") # text in a macro is just text, BAR is just more text
MESSAGE("DOG") # ${BAR} is replaced by DOG sort of like a cpp macro
MESSAGE(${BAR}) # now we print BAR which was set to CAT in the macro
