# g()('al')
`g()('al')` is a challenge whereby you need to write in as many languages as
possible code which enables the code `g()('al')` to return the string "goal",
the code `g()()('al')` to return the string "gooal", the code `g()()()('al')`
return the string "goooal", etc.
`g()('al')` is the creation of [acruikshank] who originally posed it as a
[functional programming challenge][carbonfive-challenge]. Extensive stubbornness
and misinterpretation led to its current form.
## Rules
1. __You are encouraged to break the rules, cleverly.__
2. When executed, the solution must print "goal" with sufficient o's to
demonstrate the program's functionality.
11. The code `g()('al')` must appear in the source.
1. `g()('al')` must not be a string literal.
2. `'al'` must be a string, or your language's equivalent thereof. You may
use your language's standard method of creating a string (e.x. C should
use `"`, ruby may use either `"` or `'`).
12. `g()('al')` must be a valid [rvalue] if applicable in your language.
7. `g()('al')` may not print the string. If returning a string cannot be done
in your language, you should submit rationale as to why this is impossible
for a solution which prints a string to be accepted.
642. You must be able to insert an arbitrary number of `()` calls without
modification to your solution. Therefore solutions like
[this][c-limited-calls] are incorrect.
14. `g('al')` must return `"gal"`.
If you see a complete solution that breaks any of these rules, file a bug!
If you have a solution that is close, but does not meet these rules, submit it
anyway. A close and interesting solution is better than no solution.
### Previous Solutions
The more exciting solutions are original, not applying techniques that have
already been discovered. The following broadly applicable techniques have
already been discovered:
* [Self-modifying code][c-self-modify]
* [Aborting early][sh-abort-early]
* [Human language][eng-soln]

## g()('lf')
Lets play [golf]! Submit a pull-request with a shorter solution for an already
solved language and you can get the title of shortest, as shown in that
language's [README][c-sharp-readme].
Note: I'm not done making READMEs for all the languages yet. Don't let that stop
you!
