Hello Mr Urban,\medskip\\
|
|
|
609 |
|
|
|
610 |
I just wanted to ask, how are we suppose to work
|
|
|
611 |
with the completely useless \textbf{\texttt{val}}, that can’t be changed ever? Why is
|
|
|
612 |
this rule active at all? I’ve spent 4 hours not thinking on the
|
|
|
613 |
coursework, but how to bypass this annoying rule. What’s the whole
|
|
|
614 |
point of all these coursework, when we can’t use everything Scala
|
|
|
615 |
gives us?!?\medskip\\
|
|
|
616 |
|
|
|
617 |
Regards.\\

OK. So you want to make sure that the \texttt{x}-position is not outside the
|

706 |
board....and furthermore you want to make sure that the \texttt{x}-position
|
|
|
707 |
is not yet in the path list. How about something like\bigskip

\item Scala is still under development, 2.13.1 came out in Sept.\\
|
|
|
758 |
(the compiler is terribly slow)\medskip
|
|

|
759 |
\item {\bf\url{http://www.scala-lang.org/}}\bigskip
|
|
140
|
760 |
|
|
|
761 |
\item it is a rather \textbf{\alert{deep}} language\ldots i.e.~gives
|
|
|
762 |
you a lot of rope to shoot yourself\bigskip
|
|
33
|
763 |
|
|
140
|
764 |
\item learning functional programming is not easy\ldots{}when you have
|
|
200
|
765 |
spent all of your career thinking in an imperative way, it is hard to
|
|
140
|
766 |
change\bigskip\medskip
