An expression enclosed in parentheses always results in only one value. Thus, (f(x,y,z)) is always a single value, even if f returns several values. (The value of (f(x,y,z)) is the first value returned by f or nil if f does not return any values.)

Testing for unequalness, usually != is insted done as ~=

Conversion routines are not applied for e1qualness testing so "0"==0 evaluates to false

If both arguments in a comparison is strings, then the result is locale dependent. This will possibly have consequences on servers with multiple sites, ie. multiple wikipedias on a single cluster or wikipedias on incubator.

The operators and and or uses short cut evaluation.
