Classes on stack

[Redwan]

Hi all
I'm new to D from c, cpp and Rust.

this language made me surprised because of its features and 
syntax and etc.

but I shocked when I found that classes must be created only on 
stack! Is this nightmare real? why???
I want declare classes and create instance of them on stack and 
nicely use them. why I must put them on heap??
structs does not support inheritance and I don't want to use 
them. please tell me that is not true or give me some other ways. 
I don't want define objects always on heap. don't let me go back 
on cpp :( tnx!
