The sequence for LAMBDA in the RPN code is now:
[0] ocLambda, svJump
[1] ocPush, svStringName (parameter name)
[2] ocSep, svSep
(Repeat [1] and [2] for each parameter)
[3] (body code)
[4] ocClose, svSep
[5] (code after LAMBDA expression)
Jumps in the ocLambda point to [0], each [2], and [4], which means
there are two more jumps than parameters.
For example:
=LAMBDA(x;y;x+y)(3;4)
generates the following RPN code:
index opcode type (data)
[0] ocLambda svJump ({4,0,2,4,8})
[1] ocPush svStringName ("x")
[2] ocSep svSep
[3] ocPush svStringName ("y")
[4] ocSep svSep
[5] ocPush svStringName ("x")
[6] ocPush svStringName ("y")
[7] ocAdd svByte
[8] ocClose svSep
[9] ocPush svDouble (3.0)
[10] ocPush svDouble (4.0)
[11] ocCall svByte (3)
The first parameter is in [1], the second is in [3], the body is
in [5]-[7], and [9] is where the code resumes after the LAMBDA.

Formula Helper Code
Contains parts of the formula parser used outside LibreOffice Calc code that has been pulled out from Calc's formula parser code.
Also contains some functions that are needed by code in both sc and
scaddins. Located here just for convenience. So sue me.
