Shouldn't select/reject use threequals?

Yes, grep would be a suitable alternative for `select` w/ a regex in this i=
nstance. What about for `reject` though? I feel that<br>
<br>
=A0 =A0 %w[foo bar baz].reject /^ba/ # [&quot;foo&quot;]<br>
<br>
Is more readable than<br>
<br>
=A0 =A0 %w[foo bar baz].grep /^[^ba]/ # [&quot;foo&quot;]<br>
<br>
<br>
Using `reject` also makes it so that I don&#39;t have to rewrite my regular=
 expression to negate what I&#39;m looking for. My example is pretty trivia=
l but I think that it would quickly get out of hand if trying to grep thing=
s &quot;out&quot; instead of &quot;in&quot;.<br>

It would be really handy if for instance `select` could accept a regex. For=
 example<br>
<br>
```<br>
%w[foo bar baz].select /^ba/ # [&quot;bar&quot;, &quot;baz&quot;]<br>
```<br>
<br>
I know that this is currently possible via the slightly longer syntax<br>
<br>
```<br>
%w[foo bar baz].select{|i| i[/^ba/] } # [&quot;bar&quot;, &quot;baz&quot;]<=
br>
```<br>
