DWIM
DWIM (Do-What-I-Mean) is a joke esolang invented by User:Ttulka. It features only a single instruction dwim that executes whatever the programmer has in mind.
DWIM is inspired by the hacker jargon expression of the same name, which implies correcting any mistakes the programmer has made and ensuring the code does the right thing.
Computational class
DWIM can theoretically perform all computational tasks, making it Turing-complete. However, an interpreter for DWIM would need to read the programmer's mind, which is currently an uncomputable challenge.
With the development of artificial superintelligence and nanotechnology, this issue might eventually be solved, potentially demonstrating that DWIM is indeed computable and highly useful.
Examples
Solving any popular problem in DWIM is very easy:
