Problem with sequences with variables?

I was trying to do some sequences, and it looks like they don't like variables. 
 See the following:
[user@box3 ~]$ echo $BASH_VERSION
[user@box3 ~]$ echo {1..10}
1 2 3 4 5 6 7 8 9 10
[user@box3 ~]$ echo $l
[user@box3 ~]$ echo {1..${l}}
[user@box3 ~]$

Shouldn't the second sequence echo be the same as the first sequence echo?  It 
would be MUCH more useful if it were.

Of course, this could be just a feature, I don't really know.  This is running 
on a Fedora 31 release build if that makes a difference.
