Why is this an invalid string?

str = "#$"

-:1: unterminated string meets end of file

Is there is something special about this sequence? '#$' is fine.

When you're referring to a variable with a sigil ($global, @instance),
you can omit the {} in string interpolation. Thus:

foo = "local"
@foo = "ivar"
$foo = "global"
"local: #foo, ivar: #@foo, global: #$foo"
  => "local: #foo, ivar: ivar, global: global"

So, yes, there is something special about "#$" :slight_smile:

Just to be a bit more explicit...

There is a global variable named $"

So in Siep's example, the parser is using the second quote as the name of the global variable and not as the closing quote for the string literal.
