Bugs in FromMma

Let us consider 

MmaTranslator:-FromMma(" Table[0,{n=10},{m=2}]");

[seq([seq(0,i=1..(m := 2))],j=1..(n := 10))]

The above result is syntactically incorrect in Maple language. The translation should be 

Matrix(10,2)
#or
[seq([seq(0,i=1.. 2)],j=1..10)]

up to the Mmma's result

Table[0, {n = 10}, {m = 2}]

{{0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0, 0}, {0,0}, {0, 0}}

Another bug is as follows.

MmaTranslator:-FromMma("Sinc[x]");

Sinc(x)

whereas the expected result is piecewise(x=0,1,sin(x)/x) up to http://reference.wolfram.com/language/ref/Sinc.html

In general, the MmaTranslator package is outdated. It often returns working Mma's commands as incorrect (Concrete examples are long and need a context. These may be exposed on demand.). The question arises about the quality of other Maple translations.
