Feature #9686: Syntax for symbols used in hashes

• Status: Open
• Assignee: -

[saschamayr (Sascha Mayr)]

Symbols are often used literally as keys in hashes like this:

{foo: 'bar'}

But acutally there is a little inconvenience when using the alternative :"name" literal syntax:

string = 'foo'
{:"#{string}" => 'bar'}

It would be great if Ruby provided the possibility to write the second example like this:

string = 'foo'
{"#{string}": 'bar'}

This would be logical, because you can write both syntaxes the same way when not using them in hashes.

You can write simply for that case:

string = 'foo'
{string => 'bar'}

You'd need

{string.to_s => 'bar'}

Sorry, string.to_sym.
