Creating your own keywords in java? -

i wondering if work. in java, use 'null' make nothing. work?

object nil = null; 

could use nil instead of null? thanks!

java doesn't allow this.

however, if want achieve sort of syntax whilst being able run code on jvm (and other java code), @ groovy, has operator overloading (and use dsls short syntax have similar effects using custom operators).

note defining custom operators (not overloading) big deal in language, since have able alter lexer , grammar somehow.
