<br>
I'm not very experimented in Erlang but I read carefully books and<br>
official documention.<br>
<br>
It seems to me that the guards syntax is not as good as it should be,<br>
i.e. too much verbose for multiple values.<br>
<br>
do(val1) -> val1;<br>
do(val2) -> val2;<br>
do(val3) -> val3;<br>
do(val4) -> val4;<br>
do(val5) -> val5.<br>
<br>
do(Val) when Val =:= val1; Val =:= val2; Val =:= val3; Val =:= val4;<br>
Val =:= val5 -> Val.<br>
<br>
It's boring and error prone to write.<br>
<br>
Has a "in tuple" syntax already be considered ? Something like :<br>
<br>
do(Val) when Val in {val1, val2, val3, val4, val5} -> Val.<br>
<br>
Cheers<br>
