I have been practicing the language recently, and realized that the language has a 1MiB stack size limit by default. This limit makes a lot of things impossible for the language in CP (i.e. it dies here and there due to SystemStackError). This issue has been existent on other online judges as well, and I hope to see a resolution to this issue on Codeforces (and other judges as well). The language is mostly great (The ability to write concise code is a good thing in CP after all), and I hope other people could enjoy the language in CP as well. Still, this change may be crucial for people to truly enjoy the experience, without too many frustrations.
