What's the language that takes that to the extreme? I remember it being used for fintech(?) or spreadsheets and I remember seeing one-liners that look like someone just mashed the keyboard. Apparently incredibly efficient once you are an expert in the language.
The APL family of languages that currently have commercial implementations like Dyalog and Q w/ kdb+ database. J and GNU APL are both free & open source. Dyalog is nice though even though a commercial license sets you back a grand per year (basically what most C# users pay for VS). You get a nice interpreter, support, built-in graphics, full .NET interop, full R interop, heck even DDE which is still useful in finance and my own industry. They seem to take documentation really seriously and have pretty interesting conferences. I don't code in APL, but am considering it as their product just seems pretty agile for my needs (personal user productivity). Q is extremely expensive and is the APL derived language that accompanies the kdb+ database used for time-series analysis on stock quotes...etc. It was built by Arthur Whitney and legend has it the entire source code is 5 pages of C (being an APL guy he has it all scrunched up though...doesn't like to scroll). People seem to like it and be willing to pay a fortune.
That would probably be Q used in kdb+, and J, which the previous response stated is an open source implementation of the same/very similar language.
The terseness even visible in the language name.
