Apex CASE Statement for Last Day of the Month

When using a CASE statement to find the last day of the month in Apex code, I've seen a lot of developers -- both newbie & experienced coders alike -- test for every month, when all that's really needed is to test for the shorter months, defaulting to 31 for the rest. This is a better Apex CASE statement that's easier to read:

CASE(
    MONTH( TODAY() ), 
    2, IF( MOD( YEAR( TODAY() ), 4 ) = 0, 29, 28 ), 
    4, 30, 
    6, 30, 
    9, 30, 
    11, 30, 
    31 //default for months 1,3,5,7,8,10,12
)

This example is half as many lines, and since I don't think we'll be changing the Gregorian calendar any time soon, it should be safe.
