If the `str' implementation didn't take the input sequence to be lazy,
it could figure out how long the resulting string needed to be, and
construct the StringBuilder using
Is there an idiomatic way to build up a string over different lines of
code? Or, should one simply use StringBuilder.

I would just use (str) - it uses a StringBuilder when given more than one
argument:
user (source str)

There's also (format), which I find helpful for building more complex strings.

Thanks for the response. What if you are appending over different
lines of code? Would it be slightly more efficient to use one
StringBuilder or not worth the bother.

Could you give an example of what you're trying to do? Mutable strings are
almost never necessary, in my experience.

Start with an empty vector, say v.
conj your strings to the vector at the various points in your code, so
at the end v will be something like
[this is a string]
Then, when you're done, apply str to the vector, i.e., (apply str v) to get
thisisastring
str uses a string builder behind the scenes,

I'm trying to think what your code would look

I recently wrote a program that generates complex java enums (as source)
from input data recorded
