always @(changed myvar) #10;

[very_very_log]

Can anybody tell me the meaning of the following line in verilog :

always @(changed myvar) #10;

Please do not worry about the context.
I need to undertand mainly the use of the word "changed"
(The literal use of the word (keyword ?) here)

Is it correct verilog (or SysVlog) ?

Not Verilog, at least not in the LRM version 2.2, Nov 2004.

System Verilog ?

A very early version of Accellera SystemVerilog had this. Apparently
they didn't realize that @(myvar) already meant what they were
defining @(changed myvar) to mean. When it was explained that the
"changed" was unnecessary, it got eliminated.
