The ugly truth is both don't work!<P>
[doc://eq] forces scalar context and is meant to compare <u>strings</u><P>
So in the first code you are checking if the sizes (after stringification) are equal.<P>
<c>
DB<107> @a = 1..3
=> (1, 2, 3)
DB<108> @a eq "3"
=> 1
</c><P>
in the second you have scalar from reverse on RHS<P>
<c>
DB<123> (reverse @a)
=> (3, 2, 1)
DB<124> scalar (reverse @a)
=> 321
DB<125> "321" eq (reverse @a)
=> 1
</c><P>
please stop doing weird things!<P>
you can try the (less weird) smart match operator ~~ to compare arrays.
<c>
DB<129> @a=(3,1,3)
=> (3, 1, 3)
DB<130> @a ~~ [reverse @a]
=> 1
DB<131> @a ~~ [3,1,3]
=> 1
DB<132> @a=1..3
=> (1, 2, 3)
DB<133> @a ~~ [reverse @a]
=> ""
</c><P>
a poor man's solution with eq is to explicitly stringify on both sides.<P>
<c>
DB<143> @a=(3,1,3)
=> (3, 1, 3)
DB<144> @ar=reverse @a
=> (3, 1, 3)
DB<145> "@a"
=> "3 1 3"
DB<146> "@a" eq "@ar"
=> 1
</c><P>
But this depends on the nature of your array elements, don't be too surprised about:<P>
<c>
DB<151> "@a"
=> "3 1 3"
DB<152> @b=(3,"1 3")
=> (3, "1 3")
DB<153> "@a" eq "@b"
=> 1
</c>
