I am wondering if there is any difference in regards to performance between the following

SELECT ... FROM ... WHERE someFIELD IN(1,2,3,4)

SELECT ... FROM ... WHERE someFIELD between  0 AND 5

SELECT ... FROM ... WHERE someFIELD = 1 OR someFIELD = 2 OR someFIELD = 3 ...

or will MySQL optimize the SQL in the same way compilers will optimize code ?

EDIT: Changed the AND's to OR's for the reason stated in the comments.
