Perform Math on Other Attributes?

[jonahbron]

Is it possible to perform math on another attribute in a declaration? For example...

padding-top: 4px;
height: 100px - @padding-top

Or do I need to explicitly define a variable and use it in both locations?

LESS' parser is deliberately simple and it doesn't keep track of things like that, so you need to do the latter. It would also result in a large number of reserved words, so you wouldn't be able to do this:

@padding-top: 4px;
padding-top: @padding-top;

as @Synchro said. Also bug #76 is a request for accessors (so this is a duplicate)
