Help function in rasql

[Dimitar Misev]

A help function in rasql would be useful to quickly figure out which functionality is avaialable, get quick reference for a function, etc.

Calling just help would result in a list of functions and language constructs, with function description and note if the function is deprecated. This info could be attached to query tree nodes (each node having a getHelp() method for example), so it can be easily maintained.

Calling help(function name) would give help just about the specific function.

Looks like nice to have but not at major priority, would you agree triaging it to minor already?

hm, freezing documentation into code I find difficult to maintain - and difficult to access for those who want to read about the language (assuming you don't want to duplicate documentation). This is a feature mainly useful for interactive use, so for example when ./rasql is invoked via stdin.
