Description
### The problem
delay() in lambda does not work. It does nothing, just silently skips further.
Novice users do not know that and are loosing their minds expecting it to work.
Compiler should report error like "delay() does not work in this environment." And stop compiling.

### Example YAML snippet
```yaml
I needed LED to blink to show progress while executing code in lambda. I tried this:
id (red_led).turn_on().perform();
delay(300);
id (red_led).turn_off().perform();
LED did not blink as expected. After lots of time lost trying to find out what I did wrong I finally found some explanation to other guy having the same issue and that that said delay() does not work. It just skips. That is why you cannot make LED blink this way. It turns it on and then instantly turns it off without any delay.
