[Gambas-user] Variables as functions

[Brian G]

Yes I understand this can easily be a c wrapper, but we already have on x gosub, which can be used to implement a very fast State or Event driven application. 
It would be nice if some context information could be passed as well in those situations... 

Yes I know there are plenty of work around.. 
Also adding a c wrapper also raises the issue of having to include an external c lib to the distribution. 

I do use plenty of C externs in my applications where it is expedient, but always well established Linux/BSD/Unix libraries... 

I thought this would be a very powerful and useful extension to the language. 

I am not sure if others do this sort of thing, but there you have a couple of reasons I was asking about it.
