Templates

Current boundary:

• the def-based meta family (macros, alternatives, defaults, templates) is planned for a future release; none of it is part of the current compiler surface
• everything below describes intended design, not current behavior

Templates are supposed to be mostly used for operator overloading. They are glorified functions, hence used with pro or fun instead of def.

For example here is how the != is defined:

fun '!='(a, b: int): bol = { return .not(.eq(a, b)) }

.assert( 5 != 4 )

or define $ to return the string version of an object (careful, it is object$ and not $object, the latest is a macro, not a template):

pro (file)'$': str = { return "somestring" }

.echo( file$ )
