Hello,

Is there a better way to transform a string array to a tuple or to an AliasSeq?

mixin(customSyntaxPrefixes.format!`tuple(%(%s,%))`)

I'd like to use this as variable length arguments passed to the startsWith() std function (as multiple needles).

In situations like this it's often better to define your dats as an AliasSeq to begin with, since it's easier to covert that to an array than the other way round.

Awesome, Thank both of you!

    enum a = ["A", "B"];
    writeln(a);
    writeln(aliasSeqOf!a);
    writeln([aliasSeqOf!a]);
