I meant that following keywords should be preferred to be written in all<br>
lowercase. But in our case, we lose clarity from doing so.<br>
<br>
An elegant solution seems to be to find expressive single-word keywords<br>
for our purpose, their advantage is that they can strictly follow<br>
keyword naming rules without losing clarity.<br>
<br>
It seems that mine and some other people' concerns are based on this<br>
naming inconsistency of higherThan and lowerThan. There are plenty of<br>
other good options: above/below, before/after, precedes/succeeds.<br>
<br>
I know your opinion, but anyways want this argument to be risen during<br>
internal discussion.<br>
