I just wanted to comment on the above - in my view we can not have
someclass::VAL be a constant or a function call of a function that has no
arguments. It is not that it just feels confusing but also may create
issues as a person may invoke multiple times someclass::VAL thinking that
this is a constant (cheap) while in fact it may be a method doing expensive
lookup. And my personal feeling is very much against mixing two completely
different things in this way. This reminds me of Matlab where A(4,5) may be
a function with two arguments, or a matrix lookup (things may have changed
since and may no longer be the case...).
And on a side note - the described problem I solve it in two ways:
- custom autoloader that invokes a initialization method that sets static
vars
- more recently - a class generator (as mentioned above). This gives no
performance hit as Im using Swoole and it happens only at server start.
Thanks
