Summary0007472: mixed parameter-style lists should be allowed
DescriptionNormally, a paramterized entity has some mandatory parameters and possibly some optional ones. The mandatory are usually declared first in the formal parameter list and the optional ones later.

Other languages like, for instance, Python allow the user to give the actual parameter list in a mixed style, where you would put first the parameters with a fixed place (i.e. the mandatory ones) and then can add additional ones in the named-parameter-style (i.e. assignment notation).

This way, the user does not have to remember and over-and-over again write down the mandatory parameter names, but only has to write down what is absolutely necessary while still being concise.
Steps To Reproducetake the following function header

function f(T1 mp1, ..., Tn mpn, O1 op1 := d1, ..., Om opm := dm);

The instances of this function should be allowed to look like this:

f(a1,...,an,opi := oai, opj := oaj)

 Added to draft V4.8.2 with the addition to the new restriction m): "no value list notation shall be used following the first assignment notation"

The whole restriction is now:
"m) If the mixed notation is used, no value list notation shall be used following the first assignment notation and the parameters given in assignment notation shall not assign parameters that already have an actual parameter given in list notation."

This is in line with the intention of the CR and the first paragraph of clause 5.4.2, but defines a formal rule for this requirement (otherwise we should define the semantics of a pure parameter value between two parameters with assignment notation).

Please notify me if you disagree.
