Yes but those are considerably slower, especially when you call the alias numerous times. Also, the nature of custom identifiers is that commands (loops and whatever else) are usually run before returning a value. A custom identifiers whose only function is to return, for example, a script's logo is not very efficient since global variables are more suited to this purpose and would work faster. Having never used constants/statics, I can only imagine their benefit in situations such as, an alias that calls another alias, using constants may save us having to pass parameters to the second alias. If this is made to improve speed, that would be good too
