sorry, here's again one of my crazy syntactic sugar ideas: I think it would be nice if hansl had a more concise way of writing a basic if-endif block, where the thing to be executed is just a single line.

I agree; this is something I've thought about from time to time. I
kinda like the fortran approach to the one-liner:

if <condition> then <whatever>

which would require "then" as a new keyword. We can discuss this when
we next get a chance.

Sure, having a new keyword wouldn't be so bad. And making the cross-connection with the different boolean message I just sent: maybe even introducing AND and OR (all caps, presumably) as aliases for && and || could be nice for a high-level language, like we did with TRUE and FALSE. But let's discuss this.

One more thought on this: I guess that in a one-liner no commands would be allowed, right? It seems a bit strange to have something like:

if <whatever> then ols y const x

Such a constraint wouldn't be so bad, but what about the whole "genr" apparatus as a command? Something like:

if <whatever> then a = 3

looks nice, but the explicit variant already looks stranger:

if <whatever> then scalar a  = 3

Hm.

thanks
