heredoc?

[Robin]

I was wondering if it fits into Clojure's design to include heredoc
syntax?

Or even let the user select an alternative quote character like
Ruby's: %q{this is a "special" string}

Remembering to escape special characters in strings can be repetitive
and error prone.

Could this be accomplished with a normal macro, or would this require
adding the feature to the reader?

thanks,

It would require reader support. I understand the problem, but am
concerned about user-defined-delimiters producing unreadable code.
It's also an editor burden.

That's true people could make unreadable code.

What about Python's """? It could solve the quoting problem and still
be very readable.

What about string templates and expansions?

Like Ruby's: "this is a #{template} string"

Would something like this be possible?: `"this is a ~template string"

toString() would be called on template returning a String.

Just an idea,

That's one alternative I'm considering.

String interpolation has also been proposed - I think any system must
be delimited, like the Ruby example, else the interpolated string must
be followed by a space.

String interpolation could be done via fn or macro no?

(defn template [] "foo")
(interpolate """this is a "~(template)" string""")
=> "this is a \"foo\" string"

Folks could use the interpolation that suits the task, or write their
own without touching the Reader.
