digitalmars.D.learn - Small question on: typedef get opCall;

typedef get opCall;

Does above line create a new function named "opCall" ? or is "opCall" just
another name for existing function "get" ? 

I thought typedef works only for data types, but here it seems to work on
functions too. 

Could someone please point me the documentation page for this usage.

Thanks in advance

Can you tell us which module this was in? I just tried a "Find In Files" operation on the Mango source and couldn't find it... I'm intrigued by it though, if it is in use. -- Chris Sauls

Sure, the link to the source file:
http://mango.dsource.org/structIReader.html

Link to the line in documentation is:

Link to the line in source is:

Wait a minute, the line in source now is
alias get opCall;
was it changed recently ? Althought the documentation still says
typedef get opCall;

Hehe, I just tried the "typedef get opShr" and D said that I couldn't do that. Look at this: class A { int x=5; void get(inout int blah) { blah=x; } alias get opShr; } void main() { A a=new A; int x; a >> x; writefln(x); } Maybe a bug was fixed that didn't let you use "typedef" to do what "alias" can do. It's an interesting use of alias, though, and something I never would have thought of.
