[expr] logical "and" operator, dual of [||]. Returns truth if both arguments are boolean true, and falsity otherwise. Note that this operator ''short-circuits'', and does not evaluate its second argument if the first is false. See [&] for bitwise "and".

    :   `'''[expr]''' { ''[[a b c]]'' '''&&''' ''[[d e f]]'' }`

Note that this operator does ''not'' have a command equivalent in [tcl::mathop]; use the [if] command instead.

[PL]: While there is no `[tcl::mathop]` equivalent,  `tcl::mathop::*` ''will'' give the desired result ''provided'' all arguments have been reduced to the "most basic" boolean values (1 or 0), like for instance when evaluated with any kind of boolean operator.  For example, the following code

======
::tcl::mathop::* {*}[lmap elem $listOfNumbers { expr {$elem > 10} }]
======

will tell you if all elements in `$listOfNumbers` are greater than 10.
